Just go to your sessions tab, filter for HU, 6max, FR by number of players. I think it's important to filter just by one stake because your winrate is going to drop at higher stakes obviously and you just want to find your optimal number of tables. Once you have your results, right click them and save as Sessions.csv. Open that up in Excel and copy everything. Paste it into the MTR Extraction sheet in the cell indicated. Adjust the 3 variables to your filtered game and you should have your results. The % of hands required is there to push out the outliers such as the few 1-3 tabling sessions I had that totaled 43 hands and +/- 170 bb/100 etc. Top graph is winrate by tables, bottom is hourly by tables. As is, the MTR sheet will support ~500 sessions so you'll have to adjust some formulas if you need more than that. It's not formated to look nice at all, but it does the job.
I got in a little early for the HEM2 beta testing just before the public beta release came out and tried it out for a few days before giving up in frustration with the constant crashing and huge amount of lag I was experiencing. I thought it was just my dinosaur of a PC giving me issues, but apparently people with more up to date systems are experiencing the same thing. That and it kind of seems like they've loaded it full of gimmicks that are more fun to look at than actually being helpful.
I do remember pre-ordering PT3 and being very disappointed and managed to whine enough about the HUD fail to get my money back after 5 months of "commercial" release before switching to HEM, and PT3 eventually turned into a decent product. I really don't want to go through that again with HEM2 so I'm going to wait to see if PT4 is decent. If it's not, I'm just going to be happy with HEM1 for the next year until one of them gets their stuff together.
