Normally I give advice under paid contract - so I would be happy to invoice you for my time if you wish to learn about climbing and general work-at-height.
Your biography, doodles, derogatory language, deflection, etc. is not evidence of your theory. I will take your lack of photos of the phenomenon you predict as concession that your nylon-melting hypothesis cannot be taken seriously.
If you want to be taken seriously, you need to do testing.
Touche' !
Yes, we SHOULD have some sort of drop-test-with-rope-movement
results for consideration (rather than the Nth testing of same ol'
knots devoid of detailed explanations ... --such as I recently posted
a URLink) !! Surely there become discarded harnesses, and even
newly minted ones put to the test by manufacturers --either to
warn of the vulnerability, or to tout resistance to it (say, by
incorporating high-temp-resistant Kevlar into it) !?
I have conceived of a hitch-solution to the tie-in problem
as a way to have another in multiple, safety "back-ups",
e.g. as follows ::
1) tie a clove hitch to the harness (1st bonus : this puts
2 dia. of rope through then, which might be Good, IF
equally loaded)
2) (having left ample tail...) tie a strangle knot on tail
of clove near the hitch (this will serve first qua binder
on another tail, and in back-up work qua stopper against
the hitch) ; then
3) put in a bowline with the tail --something one can do
with a "PET = post-eye-tyable" eye knot--, and then
4) tuck the eye knot's tail through the binder (strangle)
and tighten up.
.:. Now, the hitch first loads like double eyes --no running
against harness. The binder cannot much loosen, given
the proximity of hitch & eye knots on either side.
So, first the eye knot has to loosen and come untied
(which it does somehow after the binder has lost grip
of its tail!);
then a fall loads the hitch which is closed down by the
compressing of the strangle (but with rope movement,
now); the strangle would have to loosen a lot, and
then migrate off a rather longish eye-knot&tail length
of end of rope before it cannot assist hitch-holding
(though if it CAN, I surely don't expect a mere clove
hitch to be in any effective state!!).
Again, though, in part of the above there IS a risk
of rope movement, at possibly high-loading.
