Well around my home course (Par 71) where I average 73.74 for this season. I am going to use Mcilory for this analysis.
I'm going to use a system where I use my highest % of misses left & right of the fairway to determine what Mcilory would shoot.
1st Par 4 (I miss right more, possibly into trees) - Par/Bogey
2nd Par 4 (I miss very rarely) - Birdie
3rd Par 4 (hard to miss) - Birdie
4th Par 3 (Miss right) - Par
5th Par 4 (Drivable par 4, I miss more left which is in the bushes) - Par/Bogey
6th Par 5 (I miss left) - Birdie
7th Par 3 ( Depends on my shot) - Par
8th Par 4 (Miss Left) - Par
9th Par 4 (Miss right) - Par
10th Par 5 (Miss right into bunkers) - Par
11th Par 3 (Miss right of a short green surrounded by bunkers - Par/Bogey
12th Par 4 (Miss left into semi thick rough) Par/Bogey
13th Par 4(Miss right into trees) - Par/Bogey
14th Par 3 (Miss right) - Par/Bogey
15th Par 4 (Miss left into semi rough) - Par
16th Par 4(Easy fairway to hit) Birdie/Par
17th Par 4(Can drive green) - Birdie
18th Par 5 (Miss left into Semi, leaves short iron into green) - Eagle/Birdie
So on that basis & using my worse stat shots then I reckon with Rory's talent then I reckon he'd finish my ball out in anything between 64(-7) & 71 (E).
My dispersion of misses is quite good so I'm always in play & able to attack pins from such position.
