Of course there are many positions meeting the description in the subject line, but I don't recall seeing this phenomenon for this type of position before—at least, not reproducibly. I'm curious as to whether others can reproduce this result. Note: I believe that XGR+ uses a hash of the position to seed its random number generator, so it might make a difference that the score is 6-6 to 7 as opposed to some other DMP score.
