You're right it's hard to say.
I'd guess from the ground to the top of the Sickle - free or 99% free with occasional pull on gear for speed.
Stovelegs to top of Texas flake - free as above.
Greay bands - free.
Only places I could actually see aiders in use were from the top of The Texas Flake across the bolt ladder to The Boot then he starts free climbing up the flake.
Then on the Great roof.
I couldn't even see them using aiders on anything above that. Not even Changing Corners but I guess you can just pull on the bolt on the crux there.
On the last pitch they just pull on the bolts but some of them are really spaced.
All in all - mind boggling.
