Are you telling us that your 80% comfort factor is based on physics?

If so, can you tell us how physics was used to determine the 80% comfort factor, and what is the 80% applied to -- GCWR, GCWR minus loaded TV GVW, "Maximum Trailer Weight", "Maximum Trailer Weight" minus TV payload, etc, etc.
Then, can you please tell us how your "gravity, wind, levers, and all that good stuff" gives a better maximum trailer weight than the values determined by TV manufacturers.

I'm just trying to understand what your 80% value is based on and what you apply it to. For example:

In any case, I tow regularly with my 4Runner V8 Limited (rated @ 7k tow) at about 6000-6500 lbs with a full cargo area in SUV. A bit of lugging on the steep mountains, but never had a handling or braking issue.

By my math --
80% of 7000# is 5600# and
6000-6500# is 86-93% of 7000#.

Does that mean it's really okay to tow at 93% of the rated towing capacity? How about 100%?
