Where is the Decay setting?

I was prompted to change my decay setting to no decay when I logged in this afternoon to look at the days ride data. However, it changed my TP from 295 to 327. I can’t find where the setting is to adjust it back to a different setting? I’ve searched the forums, I see others have had same issue but no mention of where to find the actual setting that I’ve seen.

found it, disregard.
