> It's about an hour of your time annually, so if even at a 20% chance of success that feels like a wise investment.

At my place of work it is common for people to spend multiple days on these things, with some people on my team spending a whole week. I'm told the process was substantially more heavy weight before I got here. Maybe you are just blissfully unaware of the true costs? I would give your right arm to waste only an hour every review cycle on this counterproductive insanity! I would happily accept no promotions or raises above inflation to not go through this were it an option.
