AWS Level 7 compensation

I think I understand a few things about AWS Level 7 comp from reading here and talking to folks at AWS... 1. Base maxes out at 160k (except in SF) 2. There are year-1 and year-2 cash payments, usually around 100% and 80% of the base 3. There is some stock grant (RSU) that vests over 4 years, at 5%, 15%, 40%, and 40% Please correct the above if I'm off base. Also.. what else happens after year 1? In particular, are there additional RSU grants each year that vest on a ramp, such that they stack up and continually contribute to your overall compensation beyond year 4?
