You're saying you get a yearly refresher that adds $80K/year? After 4 years, assuming no increase in stock price or your grant, the equity portion alone of your compensation would be $320K/year.
I think he means you get an 80k refresher every year that vests over 4 years (20k/year). After 4 years, you have a full pipeline and 4 tranches (80k/year total) vest every year.
