Best estimate based on previous turnouts, weather, time of the year, etc Its not a precise science as we know. At the moment there is only one number anyway, and it would seem we now have acknowledgement that one size fits all doesnt work, or that better is possible. So adding some scope to choose a different factor may still be imperfect, but less imperfect than today.My club runs quite a few roll up, enter on the day competitions, midweek stablefords and medals and quite a few Sunday comps. The field size for these comps varies from 6 to 90. The field composition and size for these competitions is not know beforehand.
The average golfer (with an HI of 17.7) would have a CH of 21. If the comp has an allowance of 100%, they would have a Playing Handicap of 21 - if the comp has an allowance of 85%, they would have a Playing Handicap of 18.
In these circumstances which allowance should they use for these competitions in future?
