Assuming/expecting tests do show an improvement, what has given you the most gain do you think? My calculated guess would have to be the flow rate vs water velocity optimisation. There is a peaking curve in that.
I am curious about your new jet vs cup diameter ratio with regards to the jet impingment / mashing transition. Cup walls make the scenario lean heavily towards mashing. They are wider, are your cups shallower? Is the 4-6d z really optimum with the increased shear from exiting rather than sitting water ... these are somewhat rhetorical Friday night questions... better go to bed...
