No I have more bugs or performance bugs or dubious reductions interfering which result in worst case performance. But the situation changes all the time. You go one step ahead and later on you fall three steps back depends on how long you go on without a break.

For instance yesterday I played with white:

e4 d5
ed Qd5
b1c3 Qd8
d2d4 Kd7??

By the way disabling null move reductions removed the problem.
But that doesn't help much.
