I would try 2 ply first. I can believe 1 ply is doing worse than 0ply. I've seen it many times. I know it sounds strange, but as things stand now, this is the price to pay for the performance of 0 and 2 ply.

Hi I'm concerned once more regarding these backgame cubeless rollouts.
After downloading the latest build (10 Jan) and re-running the rollouts
at 0-Ply everything looked fine. As you can see from the results below
they look pretty normal with GNU doing best.
However the 1-Ply rollout looks very suspicious.
(I stopped it after 400 trials as I doubt these figures would change dramatically) Firstly the win numbers although better in the new build are lower than 0-Ply.
Secondly I can't believe the G and BG figures. This must be wrong.
In fact they look very similar to the results in the old build.
It looks like part of the bug from the previous build may still be there.
Could you take a look and see what you think.
