I thought it is common sense that the difference in strength between the major progs is quite little . So : if Junior can beat Hiarcs most of the time Fritz can beat the Nimzos and so on and so on what does it mean ? no top program can expect to do well against every top opponent IMHO . If CM beats Tiger 23,5-16,5 which would be quite significant it still would say nearly nothing about the relative strength of the progs.
