Yes, of course, 0.225 plus AP is of course something that must be tweaked. I previously suggested the range of 0.17 - 0.2 lethality, in where I take into account the expenses, wootz-steel produce, dimensions including weight, and the administered application while mounted and wearing armour (Which affects momentum). Therefore a value such as your given 0.175 is a good starting point

Statistics will become a focal point for EB2 where hopefully these kind of problems might find a better solution. The "uniform" RTW-mentality has been a limitation.
