Why expectancy, not win rate, is the number that actually matters

Most trading journals lead with win rate and P&L. I built ExpectancyIQ around a different number — expectancy per trade — because win rate alone is misleading: you can win 70% of the time and still lose money if your losers are bigger than your winners.

Curious how others here think about measuring "edge" — do you track expectancy, R-multiples, profit factor, or something else entirely?
