Just out of interest, why would you not work on your 50 yard and other pitch shots, instead of favouring leaving a longer approach.
From looking at PGA stats for 2016, the median guy (~90th/185) from 50-75 yards left the same distance from the hole as the very best guy from 100-125 yards.
Because if you ask any Tour pro what distance to they prefer to lay up to they will all have different answers. Can I play a 50 yard pitch shot? Of course I can. I prefer though to lay up at either 30 yards or 100 yards. So a nice little pitch with my GW or a smooth 3/4 knockdown with my GW. Why waste time trying to practice a distance when you have another one that is better for you.
You mentioned stats, take a look at some of these:
Mickleson who is a pretty good golfer averages 13'10" with shots from 50-75 yards, but 12'6" with shots from 75-100 yards.
World No1 Jason Day averages 13'6" from 50-75 yards, but 10'2" from 75-100 yards.
Mcilroy averages 13'5" from 50-75 yards, but 15'10" from 75-100 yards.
Dustin has his best average results with shots from 100-125 yards
Stenson is best with shots from 50-75 yards
Speith is deadly from 50-75 yards
OK, so I could go on and on listing every player, but do you get my point? A player will have a distance that works for them and it delivers the best results. There is no correct layup distance, the only correct layup distance is the one that suits you best. What you need to remember is we all hit our clubs different distances, where I may hit a GW from, another player might have a 9i/8i in there hand. They probably hit there 9i just as accurate as me, difference being is I am coming in from 150 yards where they are coming in from 120 yards.
I'm not saying your wrong, but I know my own game and how to play it. All I am saying is that you need to find out what distance is perfect for your own wedge shots.
