DislikedI think you miss understand, it's not 1.5r - wins aren't 1.5 times the size of losers. Wins are (on average) smaller than losers, but the very high number of them makes the total number of winning pips 1.5 times the total number of pips lost.

A margin call isn't likely since I'm using leverage of around 2:1.

Let's just follow it and see what happens. This isn't how I trade usually, I'm just forward testing it with microlots because that's the next step.Ignored

Still even the other way round thats more than respectable. I guess its worth a punt using 2:1 gearing,
