Cruncher Walkthrough Tutorial

The Basics

Get Callaway Handicap Scores for a Group

Cruncher starts at the “Who Goes First” Tab. This is always displayed when starting Cruncher and is a quick substitute for tee-tossing to determine tee-off order.

Who Goes First screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Golfers will typically gather in a circle to determine tee-off order. One of the golfers will take a tee and throw it into the centre of the circle. Whomever the tee points at will go first. The golfer will repeat the tee toss until the order of golfers is determined. Sometimes the tee is caught in the grass, pointing straight up or down, requiring a re-throw. Sometimes the tee points between golfers and also requires a re-throw. The spinning “Who Goes First” tile gets the job done in seconds.

Tap the Callaway Handicap Tab and, for your first time using the app, you will have no events.

After entering a descriptive name for your event (“End of Summer 2019”) then you have three choices that you can make in any order:

  • Enter the golf course pars
  • Add Golfers and/or their pars,
  • Choose the Holes to deduct for the Callaway Scoring

Here is a scenario where we will enter the scores and then pars after the round has been completed.

Enter Paul’s scores as shown below:

A couple things to note:

  • As soon as you enter a score then the focus moves to the next hole to be scored - no need to tap after every hole entry.
  • The scorecard will automatically scroll as you enter the values.
  • The Event details is showing a Callaway score as a question mark. This is because the course par information has not been entered.

To enter course par information tap the Select Golf Course button.

Since this is the first time using Cruncher there is no courses available to select.

Reuse previously entered Golfer Information

Get Callaway Handicap Scores for the next Outing

When you create subsequent golfing events, you will find that you will be able to reuse information that you have already provided.

For this next step in the tutorial you must have entered an event. We will start of where you view the list of events.

List of one event screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Press the add button to add a new event.

As opposed to the first event where we went right into Event Details, there is now a display asking if there are golfers from a previous event that should be added to the new event.

Select Golfers for Second Event screenshot from Cruncher Callaway Handicap Calculator App on iPhone

If there are no golfers from your previous event that you wish to add to your next event then press the Done button to fill out the Event Details.

However, chances are that you will be playing with golfers on a regular basis so this feature will improve the speed of creating the next event.

To add all the golfers from a round then toggle on that round.

Toggled All Golfers for Second Event screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Notice how all the golfers are now also toggled on.

There could be the situation where some golfers are not needed for the next event. In this case, individual golfers can be toggled on or off. Here is the display when Jeff and Paul will not be included in the next event.

Toggled Two Golfers for Second Event screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Notice how the overall round toggle has changed to a partial on/off state. This is handy when there are so many golfers that they scroll off the screen. The Round toggle can still toggle all golfers on or off.

Press Done with Paul and Jeff as the golfers for the next event. This will display the new event with these golfers already included.

Added Two Golfers for Second Event screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Note how there are question marks for the golfers because a raw score and a golf course have not been provided.

Since the next round will be played later, press the Callaway Handicap back button without adding an Event Name.

Notice how the list of events now includes the second event. Because we did not provide a name for the second event, it is listed as an Unnamed Event.

Unnamed Event in List screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Press the Unnamed Event in the list of events to edit this round about to be played.

Unnamed Event Details screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Now provide the event name to be Fun Round.

For the first event we entered a golfer's score and then the golf course pars. This time we will add the golf course pars before entering the golfers' scores.

Press Select Golf Course and observe that the previous golf course, Forest City National Golf Club, already exists from the previous event. If we want to reuse the golf course for this event then we could select it and then press the Back button. However, we will be adding a new golf course.

Press the Add button (+) and you are presented with a display to enter the Golf Course name and pars.

Enter the course par information for Mystic Golf Course.

When completed you will notice that Jeff had a great round of matching par at 73 which translates to a 73 Callaway score. It is a good thing that Jeff had such a great round as Paul was close behind with a 74 Callaway score.

Exclude two holes, three holes or no holes

Options to Exclude Different Holes

When the Callaway Handicap system was first created, Lionel Callaway had no holes deducted as part of the algorithm. Later he realized that good golfers could adjust their play during the last few holes so that they would optimize their Callaway score. Lionel Callaway then adjusted his algorithm to exclude the last two holes from those that could be deducted. Today, some golfers choose to remove the last three holes from those that can be deducted.

Preventing either the last two or three holes from those that can be deducted is beneficial. There is a problem if you wish to use Callaway Handicap Scoring with a Shotgun start. A Shotgun start being a tournament where all golfers are dispersed throughout the course and all start at the same time on various holes. In this case the last two holes of a course (17 and 18) will not be the last holes played by all the golfers. In this situation Cruncher provides several solutions:

  • Have no holes excluded. Although this brings up the issue that Lionel Callaway has with his first version of the Callaway Handicap.
  • Exclude two random holes that are initially hidden.
  • Exclude three random holes that are initially hidden.

Exclude either the Last Two or Three Holes

Tap the Callaway Tab to to see your list of events.

List of Events screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Tap the End of Summer 2019 event to change the holes that will be excluded. Each event has its own option on how to exclude holes from the Callaway calculation.

Last Two Holes screenshot from Cruncher Callaway Handicap Calculator App on iPhone

The button labeled Two Last Holes serves two purposes:

  • Indicates that the Callaway algorithm will exclude the last two holes and
  • Allows changes to other hole exclusion options.

Press the Two Last Holes button.

Change Last Two Holes Excluded screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Some golfers prefer the last three hole deduction variant and selecting that option will automatically calculate the displayed Callaway score.

With a shotgun tournament, where all golfers start at the same time on different holes, deducting the last holes of the scorecard does not translate to the last holes played by most golfers. This is the reason why random hole deductions is provided.

Select the Random Three Holes option.

Hidden Random Three Holes Excluded screenshot from Cruncher Callaway Handicap Calculator App on iPhone

At this point the holes to deduct have been randomly determined. Callaway Scoring or the deducted Holes have not revealed. This allows the user to continue to add golfers prior to the event taking place.

When ready to reveal the deducted Holes then press the Reveal Random Holes button.

Revealing the Random Three Holes Excluded screenshot from Cruncher Callaway Handicap Calculator App on iPhone

In this case the holes deducted are 8, 13 and 14. Pressing ok will reveal the updated Callaway scores.

Revealed the Random Three Holes Excluded screenshot from Cruncher Callaway Handicap Calculator App on iPhone

In this case there is only a change that Kevin's Callaway Score is now 74, however, note that the text on the bottom button has changed to Random Holes Have Been Revealed.

Pressing that button again will show the Random Holes that have been revealed.

Obtaining multiple Random Deductions

There is a mechanism to show your fellow golfers that you are not "rolling the Dice" to obtain a desired set of deducted Holes.

The button at the top right corner has had its text changed to "Random Three Holes". Press this button and, again, select Random Three Holes. Again, reveal the Random holes. Now 4, 7 and 16 are the deducted Holes.

Revealed the Random Three Holes Excluded Again screenshot from Cruncher Callaway Handicap Calculator App on iPhone

This had a slight impact on Callaway scores, but more important is the red notification.

This text indicates that there have been multiple resets of random holes deducted.

Notification of Revealed the Random Three Holes Excluded Again screenshot from Cruncher Callaway Handicap Calculator App on iPhone

Change the holes being deducted to be the last three holes and notice that there is no need to display a notification.
