It's more the difference between 70% and 99% rather than 98-99.

That said, you're otherwise correct. Unfortunately where we differ is in the fact that we should all be striving for a novel quality RP level, period. However, it is indeed counterproductive to spend your time bitching people out over it, or worse, finding ways to kill and full sac them for something they would have no idea how to control. And I'd have to disagree in the 'good RP breeds good RP', at least as far as grammar goes. Most folks who don't use it generally manage to be utterly oblivious to it's existence no matter how much you use it around and with them.
