Formula? This doesn't require a complex algorithm. Just elementary math. You based your conclusion on .0002 pre split value when in fact many trades went through at .0001 pre split. Arguably few if any trades went through at .0002 toward the end. The highest trade I saw was at .00019 as a matter of fact.
So even if you took the average and not the mean you'd get a value of .000145 pre split. Here ya go (.0001 + .00019)/2 = .000145. At .08 trading post split that gives you a -44.8% drop. Should I print out the math for that one too or do you see it?
