Thanks Marco for this update. Can you tell us the estimated elo improvement ? You say it is much improved. How much ?

[elcabesa]

I don't know for sure but I hope more than 50 Elo points. Vajolet had very poor tuned parameters.

[Damir]

That is very strong improvement. I hope Ingo gives it a try on his website: http://inwoba.de/

Awesome Marco! Congratulations (and thanx) for your new version. I'll update 2.4 with 2.5 for Season 2 of my tournament, should give Laser, Texel, Nirvana, Robbolito and Hannibal a good challenge for the top 2 promotion spots to the Elite League!

I think that Laser 1.5 is stronger than Vajolet but everything could happen

Nice improvement, Marco.
