A couple Go Heavy posters agree with that:
I don't care because the gear advances still put Coan 5-7% ahead of this lifter.
Not with the same equipment that Coan used. The gear in today even single ply is way stronger then that used in the past.
Jason Beck counters:
Without the bench shirt advancement, Freydun doesn't break Coan's record.
