should be more more clear on the link below

rating list with (elostats) `Aristarch 4.50 = 2600
This is just a fast and modest rating on Xeon (games 5 mn to 40/40' )
(some are still in beta testing like for Fruit SMP)
Of course are missing on my top 20
Deep Junior, Loop MP, Hiarcs ,Chess Tiger, all Convekta commercial engine
The reason is that this is very pricey to buy all of them ,
that s why I limit myself at least this year with only some top commercial engine
It could change in the future if I have a sponsor or a donation
