I don't see any other choice, Lisa, unless you could have waited and retested. it was actually pretty gutsy, as he could have been going down. Maybe the +6 is a reaction to that ?
Interesting that his nadirs aren't super low; his preshots are low. Any chance of a curve this weekend? (although I know it's hard if the timing doesn't conincide with some of the preshot numbers that are lower...)
If he just had a pattern, you could respond. Maybe a 12/14 cycle, if he was consistently low at one of the preshots.
