Congratulations to you, it takes a long time to get to 80, I think this is because 80 is the beginning of a new number, maybe you can hit 81 in less than a year. I might have hit 82 if not for the massive downvotes I got for over 6 months two years ago.
I think it will take even more than a year but let's see how it goes... sorry for the downvotes... it happened to me too a couple of years ago
You're right, it could take more, but I'm willing to bet that you'll definitely get there
