OK, I've been here since the beginning, and have seen some very strange anomalies with the weighted scoring system, but this latest one takes the cake.
My last 14 scores are as follows:29,29,29,29,29,29,29,60,61,29,60,61,29,27.
My current average is 57.74.
If we multiply the 9 hole scores by 2, all the 29's become 58's.
How exactly would my scoring average be under 58 if I've only shot one round under that number, and it was the oldest score in the series? Even if you threw out everything 60 and above, you still shouldn't get a weighted average below 58, since the lowest score was the last in the series, and newer scores carry more weight.
We definitely have to work on the difference between 9 hole and 18 hole scores as it relates to average. Clearly that one 27 is carrying far more weight than it should in the calculation.
I think one possible solution is to have 18 hole rounds count as *2* rounds recorded, since it was stated in a previous post that you weren't looking to deviate from using a 9-hole round as a basis for scoring average. That way, if you were to throw out a a 61, for instance, you'd be removing 2 rounds from the calculation, decreasing the actual number of posted scores being dropped in the last 14 rounds recorded. As it stands in my first example, all of my 18 hole rounds are being dropped from the calculations, and only my 9 hole rounds are counting toward my scoring average. Were you to drop only half of those, my average would be correctly above the 58 mark.
