But remember this: there are other factors than NPS. One is branching factor. Let's assume we habe programs A and B. A has average BF of 2 and B has 6. It is very likely that the NPS rate of A is much smaller than B's because doing more selectivity seems to "slow" things down in terms of NPS. But program A needs only 2x speed or time to reach an additional ply whereas B needs 6x the time or speed. For two additional plies the figures are 4x and 36x. Even if doubling speed results 3x increase in NPS for B and only 2x for A we can see that A earns more from speedup in terms of plies - in terms of strength, who knows. So again NPS doesn't tell you much. Severi
