Agreed but points per win changed during history so win rate is the simplest calculation. The ratio of draws or points to wins doesn't alter much over a long period so you don't get very different information by delving into the details.Win rates don’t tell the whole story.
League position, points gained and losses also matter dramatically. If Spurs win 5 and lose 5 then they have a 50% win rate. If they win 5, draw 3 and lose 2 they still also have a 50% but less than half the losses of the former.
It’s why imo you need to look at more than just certain stats when judging a manager
I think we've all got used to a very low scatter on outcomes recently which is causing an over-reaction to one (very) bad patch.
