I don't see Genius3 in the last SSDF list, but I do see Genius5 on P90. And
Tiger 11.8 was tested on P90 too.
Tiger 11.8 P90 -> 2483 (+54,-52)
Genius5 DOS P90 -> 2431 (+18,-18)
(number between paranthesis are error margins)
That means that with a good confidence:
2431 <= Tiger 11.8 P90 rating <= 2537
2413 <= Genius5 DOS P90 rating <= 2449
In the worse case Tiger 11.8 is 18 points below Genius5, in the best case it is
124 points above.
The most probable is that Tiger 11.8 is 52 points above Genius5.
I expect Tiger 12.0 to be at least 25 points above 11.8, so you are probably
right: Tiger 12.0 is probably 75 elo points above Genius5.

You are right.

Yes. I think we can achieve this just by exchanging ideas and selecting the best
ones. I'm not even talking about finding new ideas, and we DO continue to find
new ideas. Exchanging ideas is a kind of brainstorming, and new ideas appear
from time to time.
