The reasons that the time control is relatively short are twofold: 1) The development team wanted to make the games short enough for the human testers so they would be more willing to play all 30 games required for the test. If the time control had required a longer time commitment from the testers, they very likely would have received less data. 2) Over 13,000 further comp vs. comp games needed to be played to complete the testing and get reasonably accurate ratings for all of the personalities. At 5/10, the testing was done literally a few days before the program was finished. Obviously, then, a longer time control would have caused the ratings testing to not be finished within the deadlines of the main program. jm
