Thats where the time+setup comes in. Dealer that put ours on spent probably 2-3+ hours checking, and calibrating the rowflow until it was dead on at 5mph.
IF you calibrate for the delay in the clutches and the time it falls down the seedtube, it'll be spot on everytime (assuming you keep your MPH relative to the calculated speed).
