Meh, it's been my experience that those charts are borderline worthless. The truth is promotions are probably only fractionally about performance. A lot of it is budget, creating pr/"buzz" [even if it's proportional to impact], did you happen to be on a revenue-generating team, is there any political risk to promoting you (e.g. would you say the type of things I'm saying right now?).
Maybe google or something is different (and I doubt it), but that's less than 1% of engineers.
You need to be able to read this one. I've gotten a lot of props for being someone by bosses can rely on to challenge them. But I also don't do it for stupid things, and if they seem to not be willing to flinch then I back down.
