It is very easy to calculate what your handicap index, course handicap then playing handicap will be under the WHS (there will be charts for this when it comes in)

Look at your handicap record, take the best 8 gross differential scores from the last 20 divide by 8 and you have your handicap index (round to one decimal point).

Find out the slope index for where you are playing (

https://ncrdb.usga.org/ ) divide this 113 and multiply by your handicap index, round to a whole number and this is your course handicap.

For a singles strokeplay comp the Course Handicap is multiplied by 0.95 to get to a playing handicap (0.4 goes down and 0.5 or better goes up).

From all this I would expect to see about a 2 shot difference at most depending on what the decimal figure is in the last calculation.
