I'm sorry, it seems we are talking about very different things&
I'm telling you that particular statistic takes more than 3 hours to calculate and suggesting the easy way to speed it up to 15 seconds - modify Results page.
Maybe I could get you wrong.
Which way exactly can I add some columns to the "Results/Tournaments/By Buy-In" page?
I just need mathematical statistic of ROI
It doesnt matter technically for me - would it be either PT4 statistic in "My Reports" , or just a column at PT4 "Results/By Buyin", or anywhere else
It only matters that I could get the data within a minute. and be easily useful.
Still feel two new columns would be the best solution
