Call them "tied" if you like, but acknowledge that by "tied" you mean not that the plays are equal but are very unlikely to differ by more than some small amount.
Yes, that's exactly what I mean.
In Nack and Paul's Opening book they use the phrase 'tied' when two plays are within 0.010 of each other.
Let's say you have two plays that are 0.002 different, but you've done enough rollouts so this is a statistically significant result. Which is more accurate? (assuming you can't mention the exact interval):
1) 'Play A is better than Play B'.
2) 'The plays are tied'.
