My guess: playing precision you're getting to game without revealing your hand. I don't know how much relay stuff you play but this may be benefical to your slam bidding. This must result in big gains on game hands. Precision handicaps your part score bidding though - less space to diagnose the right contract. Losses in part score are more numerous but gains from game are larger.

I think it important to bear another point in mind.

The statistics are of small samples...

Ya I was beginning to notice that the sample was small. For Justin and a number of others the number of hands was 300-400, so about 75-100 hands declared. If the standard deviation of IMPs/board is as low as 3, then the standard error will be around 0.3 or 0.4 or so. That means a fair amount of variation. In my own datasets, when I do any kind of breakdown I tend not to jump to conclusions unless I'm including at least 1,000 hands... and for some measures (like slam performance) I need a lot more because they happen relatively frequently.

Still some data is better than nothing, and if the trends hold, perhaps there's an explanation for it -- probably some combination of the things we've identified plus 1 or 2 others we haven't.

The 2 links I found had 235 and 704 so 939 hands. Point still remains though.

Now we're talking about close to 250 hands declared, so I think it's reasonable to say that there's something to this. Who were your teammates in 2011/12 out of curiosity?

It looks like it was Hurd and Woolridge. They were setting a lot of contracts at the other table (about 42.5% vs. 36.5% average for the field). This might help explain the strong I/bad statistic; I:pad should, I think, be independent of the other table. Anyway, it's reasonable to assume it had something to do with (1) finding more making contracts that the opponents your way did not find, and (2) finding more good sacrifices than the opponents your way.

Maybe it means that you are getting away with way too much. Maybe going down 50 a trick often, opponents aren't doubling enough, or selling out too easily. Note to self: be ready with chopper when Justin comes to table
