For me the test for speed is the verification of time that two logics ask for solving the same position. I must verify big number of positions in order to be certain that response is not aberration. And deposition of big number of different positions, taken very often from different sources, take time. To give you one idea about aberration. The last time I verified the new logic on the first 20 position, just asking the game to play on its own. The speed improvement was 160%. After this I took the positions from the Chess Life and tryed the same there on around next 18. Advantage was hardly 10%. Where I am? I still don't know. Tomorrow will continue my verification.
