But, at least in my local league, we have probably 200 people you see regularly at the mini's during the season. Several touring pro's, handful of guys floating either side of 1000 rating (not me) and a ton of competitive players. I would guess the average, repeatable on command max distance is 320-340 for those 200ish people. Absolutely everyone of them will swear up and down they can throw 400'. If you took them all out in a level field, no wind etc ... I would give my next paycheck away if more than 20% of them could. 400' is a long freaking way. It's a rare person that can hit it without concentrated effort. 550-600' is for genetic freaks who also put a lot of practice in.
