Not directly related, but that comp ramp-up between years 1-4 and 4-6 seems similar to what I see at my current place, which is starting to cause some discontent and potential retention fun down the line, with people getting used to everything ramping up quickly initially and then slowing down once they get to a more mature level (and title changes get further apart too, since you're expected to do more and more at each role).

Interesting to see similar numbers from elsewhere.
