Yes, it depends very much on your driving style if the pacenotes are good enough or not. For example, I've learned to be very sceptical on crests, and if I don't know exactly (because I've seen it, or know it, from restart #323908) where the street goes after it, I wont full-power over it.
There are just some situations where it's like:
"Flat left ... over crest ... ... ... INTO ... ... (hey we have the time, right?) ... ... medium right 30"
And then you see the medium right corner somewhere below you. You could argue that I should up the callout distance, but then twisty parts get totally confusing. I think callout distances should be dynamic, depending on your cars speed to some extent. A real life co-driver would also call out that medium right far earlier, not at the moment of your wheels leaving the ground.
Also the difficulty variance of certain callouts is unnerving, too. Sometimes "easy right" is a quick flick to the wheel and that's it. Sometimes it requires major slowdown to prevent wrapping yourself around a tree. I gotta love those sloped fast lefts that actually require driving like a medium. And these problems get like tripled if there's rain to top it off.
