MTF10 has little to do with glare. That's a different test setup which we haven't done (because it's not trivial).

Well, with my little experience I should say that there is correlation between MTF10 MTF40/50/60s and glare.
1. Tokina 100 macro comes in my mind. Razor sharp test charts pure contrast. Real life experience – this lens glare as a hell.

Page 17 Mr. Nasse gives also an example of glare and relation between MTF10 and MTF20s and 40s. BTW at the same page Mr. Nasse is bashing all measurements based on single point MTF e.g MTF50
