Further thoughts:
At time of writing, 156th place is 7 under (64), which means one more sub 64 and the highest qualifying score will be -8 (63). The -8 scores currently occupy 109th to 155th places, which means 48 more sub 63s and my 8 under will no longer be good enough. (used the Srixon Z star for this round, doesn't go as far as Callys, but perfectly acceptable)
My earlier formula for the cut is incorrect as I did not account for the variable that is the brilliance of the sub 60 shooters (including B. In B. - only 2nd - must try harder).
Also it's only day 2 of qualifying.
Also last year we didn't have the calloways to help, so revised cut IMHO will be
62 (-9)
Or to put it in a formula
My best score - 1 (boo hoo)
As mentioned in an earlier post, there is very little run in the fairways, and flop shots are not going as far as on other courses from 30% - 40% rough and sand.
