Perhaps, for example, an E3 at Meta can go to E4 in 2 years, but an E3 isn't making 300K total comp at Meta in California to begin with, nor would they go to 500K after promotion.
If you're a hiring manager then I don't need to explain to you that a 50% increase even with the highest ratings isn't some normal thing that happens.
Maybe you've seen it happen, I believe you. My point is that it's not the norm and you should stop saying it like it is.
