Well I'd question those results first based on the fact you have detailed which AS version, but not the ShinEtsu version? I'd also question the results based on application, and even source.

now I forgot to say what I was going to say so here it is :

what about that other thermal paste?
I forgot the name but I'm sure some of you will remember it.
I believe xploited titan uses it.
early versions had problems with the copper from people's heatsinks /-blocks corroding
it's a phase-change'ish paste (not to be used under phase change cooling)
