For the
Cessna 172N, at sea level, 20 degrees, maximum take-off weight, TORR = 835', LRR = 530' - a difference of 305', or, to put it another way, the TORR is over 50% greater than the LRR.
The difference between TODR and LDR is not quite as great, "only" 255'. But these differences get markedly bigger at higher altitutes. I will grant you that the differences are smaller on grass runways... but I think I've justified my ealier post!
