from my experience at google. everyone is so obsessed with promo that no one does 20% projects because it distracts from their main project and hurts their performance review and delays their promo. its not even 120% time because if you have time to do 120% you should just do it on your main project to get faster promo instead of something your manager wont care about or know how to evaluate in a perf packet. the only time people did it was to try to switch teams. or if their main project was low impact/easy to do in 80% of your time so you wanted to pad perf.
