Not to me I guess that all these lists except AEGT are blitz and the gap in AEGT is the smallest. Ruffian may be better in blitz than Aristarch but not better than it at longer time control. I believe that the rating lists that you give are based on ponder off games. WBEC is based on ponder on games and I read the following rating list by Frank quisinsky in the arena forum based on ponder on games at 10/40 time control. 4 Aristarch 4.50 : 2685 54 53 130 58.1 % 2629 8 Ruffian 2.1.0 : 2657 58 45 130 53.8 % 2630 33.8 % Uri
