Absolutely correct. The key is the maximum distance from both sides of a center point of blade contact to terra firma. Makes little difference whether it is at a center point beneath a tractor with 96" between wheel bases or behind a tractor on a three point floating with the same center point. Take a blade and put a "rider" wheel off the back and you'll be amazed at the eveness you'll get from a driveway. Anything to remove the up and down repetition of the tractors travel results in a smooth outcome.
