Appreciate you taking the time to put all this together @calamus056. I always prefer to back up my "gut hunches" with actual information...
As a matter of mathematical correctness, you might want to re-do your negative percentages... you can't have more than -100% because that takes you to a negative number.
For example if something went from $100 to $40, it declined by 60% (40/100, then subtract the result from 1 and multiple by 100 to get a percentage), not by 150%.
Ah thanks, i'll fix the negative numbers. I knew the formula obviously, i just haven't slept much and was working on it for too long so then your brain stops working hehe.
No worries... I'm sure this is a LOT of work to compile!
