Sorry that a on-site training has delayed my response. I think there's a grace period for implementation in most specs., so you may want to ride it out if you have one.

I plan to wait until summer before having the code re-written for the curve solvers EI offers. Until then, the x0.77 conversion of Dr Kirk's Excel based solver and the Peensolver webapp will not work correctly for entered values between 0.0001" - 0.0050"
