I put 4" by 7" plates on my 12 and 20 ton presses.
I pressed a Z of BH on both after pre pressing in a 3" by 5" mold.
I did 4.5 min at 190 f and had to do 2 extra minutes on the 12 ton press.
Both got about the same amount but the 12 ton press took 2 minutes longer.

I re pressed everything at the end ...
and leaving nets flat gives better recovery than folding them and re pressing ...
