Low Z3 R2?

Hi jcl. I'm seeing on 1.34.1 that Z3 Tests to a quite low R2 value - is this correct? I don't remember seeing this on earlier versions; and the Equity curve doesn't seem to be that bad... Or maybe it's my incomplete understanding of R2...

Thanks.

Yes, R2 is low because the equity curve is not linear. It is steeper at the begin and more flat at the end.

Thanks jcl. Evidently R2 is much more sensitive than I realized in distinguishing linear from higher order & non-poly curves...
