I haven’t provided the output, but I ran 0,1,2,3 plies (Same filter and other settings). In those instances Cache Evals = No Cached evals, which leads me to believe we still have an issue with plies >3  with caching that hasn’t been discovered. I will look at the code more tonight and if I see anything I’ll let people know.  My guess is we have missed something small somewhere (I hope).

It appears we may be dealing with an optimization issue. Stay tuned.

Its not optimizations. I can’t reproduce the problems now. I know there is something that will cause it, I just don’t know what it was (So I am positive there is a bug, I just can’t reproduce it). I am betting it has to do with Pruning analysis options.

On a side note can someone briefly explain “fTop” variable. There is an inline comment in eval.c from a few years ago that fTop should be in the cache but there were no available bits.
