I am still stuck on the recommendation for a rollout without a minimum number of trials or a very low minimum number of trials regardless of what the bot tells you the rank is. For example, randomly doing rollouts today I saw this:
1. | Rollout1 | 13/10 11/10 | eq: -0.113 |
| Player: Opponent: | 44.06% (G:25.07% B:0.66%) 55.94% (G:23.59% B:1.42%) | Conf: ± 0.055 (-0.168...-0.058) Duration: 2.1 seconds |
|
2. | Rollout1 | 24/21 23/22 | eq: -0.337 (-0.224) |
| Player: Opponent: | 42.55% (G:13.25% B:0.23%) 57.45% (G:22.27% B:0.98%) | Conf: ± 0.089 (-0.426...-0.248) Duration: 1.1 seconds |

That's right, 2 games and it reports 100% confidence, so I can be done right? Of course not ... but that seems to me what Daniel suggested we could get away with in this thread.
How about after 20 games and 95% confidence, good enough? Still I say of course not.

72 games, 99.7%, when should we say enough already, the bot is certain, can I quit wasting my time and move on to another rollout? Again, I don't know, I have done zero rigorous studies but if all that someone took away from reading my posts is that 324 trials is a minimum I'd be quite happy with that.
