That's the best you can do in PT4, afaik, because tournament reports can't include this kind of stats. (Per-tourney reports group hands by tourney - there's a
GROUP BY tourney_summary.id_tourney clause in the corresponding internal SQL query - so stats that summarise per-hand DB entries in a non-standard way can't be used.) I made an 'all hands report' and aggregated the squares of net chip winnings in every hand like you.
I also agree that the cEV is skewed.
The 'EV difference' (between the cEV and the actual chip winnings) is not very skewed because e.g. 70/30 flips in Hero's favour happen about as often as 30/70 flips in opponent's favour for about the same pot size. But
the actual chip winnings are somewhat skewed positively because they're either +1000 or -500 for a single tourney. Hence the sum of the two stats - the cEV - is skewed positively.
Get well soon!

I got something between 350 and 400 (don't remember exactly) for iPoker Twister cEV, but that's because it has big antes in the second level and is thus more conducive to coinflips. For WPN's Jackpot Poker that has a healthy 15/30 level, your SD looks plausible. Thanks for sharing it!
