Since you can't be arsed to do any research to support your point...
Hayden - Motegi - QP 2011 - "We weren't able to continue from the good start we had yesterday, even though our times aren't too far from the second group. With the cooler track, I didn't have the same grip, and I was spinning quite a lot on the edge of the tyre. This afternoon, we also picked up some chatter that I hadn't experienced all weekend, which made it really difficult to go fast."
28/32 degree track temp for fp3/qualifying compared to 41 on the previous day & all of a sudden it's causing chatter?... unheard of!... it j-j-j-just flies in the face of conventional wisdom!
Andrea Dovizioso - Qatar test - Feb 2008 - "The bike is competitive although we have to reduce the front-end chatter that we have experienced tonight, which has disturbed me a little."
Night time test reaching a around 15deg air temp... chatter not experienced in previous test.
Clearly none of them have a clue what they're talking about either but you, expert that you are, do.
I suggest that you can't find a single quote saying that low grip conditions can't accentuate chatter for the simple reason that no-one knows that it can't... & there's the evidence that it can of course.
