PaulTon: alosso: You must not shoot better than 35/70
35/70? His avg is 61.04, surely scoring anything higher than 31/62 will have no effect.
Sorry to say, I think that you are probably wrong. It's due to the non-linear characteristics of the saturated average. There may still be some higher scores in the mix, and he'd have to avoid to kick these out at any cost!
As an example, my last TM score pool included fifteen 64s but only one 58 and
five 60s. Plus, I gained 1.4 from two Match wins. In the moment before the change, I stood at 61.5 and any 63 would have dropped my average.
We don't know the precise mix of the Lgacord, but apparently he has played more sub-61 scores on "good" courses than I (exclude the numerous Par3 scores). Thus it's well possible that there are 65s or even higher scores included. Replace one 65 by a 63 and he will gain 0.04 in average, enough to tier up!
After this analysis, I'd even give 37/74 as a more likely safe margin!
But, what fun can it be to play above Par deliberately?
