Yeah I probably don't understand this concept, I mean I only have about 75 pages of notes generated from the Destroyer myself. My goal was to post scores from the destroy the 1st, 2nd, 3rd time etc, to gauge your improvement and understanding of the topics and eventually compare them to the DAT scores in the future. I feel that this will give other students a resource to see if there is a difference in scores in the people that use Destroyer and those that don't. I read each and every post of DAT scores on this board to see what people have used and if it helps. This may not help me, but if it helps others in the future I would be happy to do it.
