I have implemented hashing 2 bounds after reading fruit does this. It is fairly complicated to do and I just want to see if it is done wrongly. I measured the figure hash-hit-return-by-2nd-bound/total-hash-hit Per game move it is 0.000 almost all the time. Ocasionally it has 0.001 and almost rarely 0.002. If others have much higher figure then this,I suspect my double-bound is done badly. It is difficult to debug except through usual hit statistic. Vasic, If this 2nd bound statistic is correct, then fail-soft propagation of exactness is far better. For full-search FL exactness,it starts from 2/3% and drops to about 1% for whole game.
