Hello everybody... brand new here... I play in a local club and of course we think we have a problem with people inflating their handicap indices with rounds outside the club.
The person in question over the last 5 years has played 208 rounds outside the club with an average differential of 17.7. He has 35 rounds within the club with an average differential of 12.5.
The break down year by year is:
2011 (22 outside rounds, avg diff 18.1 vs. 6 club rounds, avg diff 12.0)
2012 (34 outside rounds, avg diff 21.2 vs. 5 club rounds, avg. diff 14.0)
2013 (61 outside rounds, avg diff 17.3 vs 7 club rounds, avg diff 13.7)
2014 (52 outside rounds, avg diff 17.6 vs 11 club rounds avg diff 11.1)
2015 (39 outside rounds, avg diff 15.4 vs 5 club rounds avg diff 12.8)
I guess my question is this:
Is there any other logical or plausible explanation other than sandbagging?
