I've not seen anything over 7 on mediums, and that was using UT-1000 steel (absolutely perfect according to schematic) with great/amazing on the assy/experiment. I'm at a loss to explain how anyone could possibly get more, since getting amazing on initial assy yields apparently the same base efficiency of 29 as the Great, and still caps at 70 with amazing experiment.

Gas has no UT, so shouldn't be figured in at all.,.. right?
