Error in reported annual return

Collective2 reports two different values for the annual return of my system. Here are the values that are reported at the following locations:

123.8 main trading system website

123.8 TOS website

123.8 The Grid

97.1 Most Popular Systems website

97.1 Hot Systems website

97.1 Hot Stock Systems website

What is the reason for the difference?

One figure is compounded, one is not.

I agree this is confusing - the two figures aren’t always labeled clearly. I hope to be able to make it more clear which figure is which (compounded or not) in the various stats labels.
