It seems to me you might want four pools of cars . . . and you would want at least one standard deviation, if not two, extra cars in these pools to create variety .Not a bad idea, Allen, but given the sort of data we have I would be entertained to see a calculation of the Standard deviation . . .
But I take your point, that we DO need rarities so that our trains will exhibit those rarities.
