Hair growth timeline - should my results be 80% done at 8 months post-op?

Hello: Researching online and seeing posts on Real Self, it appears that people 8 months post hair transplant should have 80% growth. I did FUE in September 2021. All 5 consulted HT surgeons all agreed on the same exact number of grafts (3500 grafts) need to produce natural looking thick density. However, at 8 month my hairline is still see through. Should my results at this point be 80% done with the remaining months producing 20% growth & change?
