I went out today and tried to see if I could tell. Coasting downhill, I have left foot forward mostly. Through turns, usually my outside foot is down and my inside foot is up.same.... never actively thought about it.
That's my white whale me thinks...i generally switch which foot is in front about every 20 seconds. it started many years ago from getting smoked legs from downhilling in the same position. i've always switched forward feet for turns, but it took a good while to be comfortable letting myself takeoff and land with the opposite foot forward...
