First, the post is correct. Jlall is two time-reigning World Junior Champion. See this
website for details. Technically, over the last 1000 boards, justin is not averaging 1 imp per board. In fact, his current average over 4404 boards is 0.69. There is a reason for this, he plays a lot of team matches against evenly or closely evenly matched teams.
But let's deal with the statement that no one could average +1 imp over a 1000 boards without "help".

And I still believe an average win rate of over 1 IMP per board over 1000 hands is impossible without some form of help, be it cheating or psychic powers or devine intervention.
Here, I will show you data from OKBridge for the partnership of papi and snabu... In the one database for them I checked (bridgebrowser online has a papi database with all the hands he played on okbridge over several years). This partnership played thousands of hands, i stopped at 10323 hands and their average was +1.02 imp/board. I hope you are wise enough not to suggest this partnership was cheating.
I am leary of posting similar numbers for bbo members, since the implication you state is that to have those numbers they must be cheating. Also, it is hard to find partnerships with 1000 boards together, as i have to search multiple databases (BBO plays more hands in one month than okbridge does in a year, so each few months results in the creation of a new BrBR database for BBO data). I will however give you three names from the BBO.
SusieQ -- a very nice canadian and recent gold star, 1324 hands, average imps, 1.49. A lehmans of 51.37. (BTW, dank, susie's regular partner averaged 1.36).
luchi2004 -- an Argentine gold star who won the South American Open Championships, has played 4444 hands, averaging 1.15 imps, a lehmans in the mid 60's
winkle -- a forum poster here and nice guy from the Boston area I believe (and non-gold star), he has 2112 imp hands, averaging 1.01 imps.
I can assure you these players are not cheating. Now, obviously, as uday pointed out, cheaters pop up to the top of such list. The really high-and-mighty cheaters go much higher, and have averages in the 2 to 3 imps per board range. These people are easily caught and banned.
However, there are literrally 1000's of bbo users with averages above 1 imp that don't cheat (and many that did and are now banned).
You simply can not look at myhands (or bridgebrowser) and average imps and decide guilt or innocence. You seem to continue to overlook the fact that some people self-select their opponents (friends, students, favorite victims). If I were to always play against some of my friends, i would average well above 1 imp/board, if I were to always play against others, i would average below 0 imps. This is EXCERBATED when playing in team games.
I've heard the argument that if "world class players" can't average 1 imp per board, how can crappy players do that if they are not cheating. The reason is simple. The world class players self-select to play against other excellent players (either in team matches or main room). The same thing happens. If a bunch of bad playeres play against each other, the better of the bad ones will have a high imp average.. imp scale shows relatively difference between the playing pairs. In the long run the better pair wins, and size of the win depends upon the difference in the relative ability. You keep thinking random opponents, and want to turn off some software features. People keep telling you that BBO is a social site and friends hang togehter and play together. This self-selection defeats your concept. There are beginner/intermediates who play in the BIL who average more than 1 imp because the people they play against are much weaker than they are.
