Hi Sundance. My experience has been that the Z systems sometimes Test very differently from version to version. For example, 1.26 Z3 Tests very differently than 1.24.

My understanding is the correct procedure when upgrading is to first Test to find the Margin/Risk setting that gives the same CR as you started with. This is the procedure I'm following, as described in the spreadsheet posted in the other thread.

If this is incorrect, I hope someone will chime in!

HTH.
