Anyone keep historic data on their HP/Iso sales?

Trying to get a gauge on when to 'expect' the next one. I know it'll never be 100% predictive, but curious if there's any sort of pattern to it.

For clarification, I don't mean how much $$ they make, I mean when they offer more HP/Iso for less money.
