Freestyle Any way to predict prop pitch based on nozzle sizes?

[CARBONX2]

My ski with a DASA 1200 and Maxx 155 pump and 8/16 impeller gets more height with 86mm nozzle than a 90mm nozzle, and still revs out easily. You can hear it slipping a lot with the 90mm. The impeller is good, with 0.3mm clearance. Is there a way to predict what pitch to run with 90mm based on how it runs with the 8/16 and 86mm?

If it runs good with the 86, why change it?
