Rob, Sunny, we're possibly just going in circles here, but I'll have another go. My understanding was that Rob discounts strength and/or size (yes, I changed to using fitness, my bad) when discussing skill.
Now from a technical point of view in terms of performing a technique under controlled conditions, I'm fully in accordance with this view. Where I felt we differed is that when you take into account a "real" (tm) confrontation, strength and size will have an impact as well as skill and that you cannot discount any of the three (here of course you can include terrain, numbers and whatever else springs to mind). Robs one-liner concerning high levels of aikido seemed to indicate another viewpoint.
