I have take some time off from programming Nirvana and thus now I have some free resources in order to try out an idea I was toying with previously. This rating list is not meant to be serious but is more for seeing how different engines scale with added time. The ratings are set such that Arasan 16.3 is at 2790 elo. This rating list uses a modified version GBDC12013 with only 100 opening positions. This allows for each engine to play both sides of each opening five times against each other.

Interestingly enough all of the engines that are rated below Nirvana on the CCRL list seemed to have performed about the same at this hyper speed but the rest out performed their ratings drastically. Granted this is only against Nirvana which I suspect as being very poor at very short time controls.
