I can add that Fritz3 already got an IM norm some years ago when it used p90.

In that case I know that the GM's did not special preperations and could get a
draw in the best case when some masters did special preperation and could do
better.

Fritz3 was commercial and I guess that it could do even better without being
commercial.

I believe that your program has not less knowledge than old Fritz3 and if Fritz3
could be close to 2400 on p90 then I see no reason for you to assume that quark
cannot do it.
