I do not think that it is so easy to do in 3 monthes a 25 elo improvement(the
differenece between tiger and number 2).

You can look at the improvement from Fritz5 to Fritz532
they had more than 3 monthes and they did only 13 elo improvement.

Nimzo732 had also more than 3 monthes and they did only 19 elo improvement.

Junior6 had more than one year and I guess it is not going to do more than 100
ssdf elo improvement.

I agree but in this case there are also disadvanteges.

The dos version is slower by 8-10% relative to the windows version because the
windows version has a better compiler so I do not think that the final result is
going to be clearly different.

Tiger also does not use nalimov tablebases and it could probably earn 10-20 ssdf
elo rating from these tablebases.
