Win rate on its own tells you almost nothing
A 70% win rate sounds excellent until you learn the average loser is four times the average winner. A 35% win rate sounds broken until you learn the winners run.
The pair that matters is win rate and payoff ratio together, and even then the median trade tells you more than the mean, because the mean is hostage to your best few trades.
When someone posts a strategy result, the first two questions worth asking are: what's the average win divided by average loss, and what does the distribution look like without the top three trades?
