CAGR variable for objective()

What is the best way to obtain CAGR for use within Training mode's objective()?

I was looking at the following but didn't find CAGR as a variable:

Thank youu

CAGR is a metric for reinvesting strategies. It cannot be used as training objective because you don't reinvest when training.

Ah yes, thank you for the reminder. Guilty as charged : )
