KY1792:I just recently moved up to tour pro.
Congratulations!
KY1792:My scores dropped 10 shots.
Congrats again! You scored 76 at Merion as a TP, while the best Pro score was 86.
=> MER, (average -0.5, only one round as TP), best score -10 !
Regarding the other courses, any complaint to have lost skills is void.
At STA, your average score rose only by 1.4, the best scores rose by 4.
RSG, average -0.45, best score +4.
CCC, (average -5.7, only one round as TP), best score +2
(all numbers for 18 holes, 9 holes x 2)
Thus you "lost" a maximum of 4 strokes which can easily be explained by the hotter greens. Adjust your putting length, tap in the second putts, it will become sunny very soon!
