Options are all about having both slow speed and power at touchdown. Slow speed allows us to truely choose the touchdown spot and power allows us to truely control the descent rate. Only full flaps truely enhance the slow rate of closure and the sink rate that requires power to control it.
My apparent brisk walk rate of closure approach is much like the normal descent angle MAF approach. It also works with the much steeper but slow power pitch approach that hotrod180 uses.
The guy who uses both power and pitch will get down shorter, other things being equal. Power off spot landings are good practice for forced landings. Power off and/or less than full flap is not good short field technique. Too much energy management is given up.

Did it twice, witnessed by a 182 back country pilot with 2500 hours, he agreed, touchdown speed was 20 mph max. We are both bike riders so we know what that speed looks like. I attribute this to UHGE, UpHillGroundEffect.
