Did someone forget their % sign? An F15 being 730% as effective as a Mig21 I can just about believe.
It is an indication the ratio of the scores used to evaluate individual effectiveness of two platform does not translate to how many of one platform it takes to equal the other in combat.
In the example I cited, The algorithm did really give the F-15 an effectiveness score 730 times higher than the MiG 21. Yet the only thing that really says is an single F-15 is much more effective than a single MiG-21. It does not mean a single F-15 from 1975 can realistically hope to prevail in a simultaneous engagement with even 3 competently flown MiG-21, much less 7.3 or 730.
