Three years is about the experience I had when I still used Micron for bottom paint.
Tip for you paint job in the spring: As a first coat paint the forward third of the hull, the forward half of the keel, and the forward half of the rudder with a contrasting color of paint. I use blue as a first coat under my red bottom paint. The contrasting paint is your "signal coat". Then paint the other costs with your preferred color. When the paint is sluffed off to the point that the signal coat is visible, it is time to repaint the bottom. I'm surprised that the base of the barnacles didn't get removed by pressure washing. But then you paint had exceeded its life and the copper was probably completely leached out of the paint. Try taking a 1 1/2 or 2' wide wood chisel to the base disc of the barnacles. Lay the edge of the chisel along the edge of the disc with the chisel almost flush with the paint surface, and give the chisel a thump with your hand. The disc should just pop off. That's has worked for me since I was shown the trick by a yard mechanic several years ago.

This haulout (season #4), the bottom was infested with barnacles....not a few scattered around, a significant number all over....I wet sanded, which removed the most of the little critters (and a lot of the 66) but there are still traces of the 'little critters'. Not sure if I will sand them out completely or simply paint over them next Spring. Anybody have this problem and how did you finally deal with it? On a further antifouling paint story, years back in the Binnacle, a fellow sailor/racer approached the shelves of antifouling paints....he stops and pulls out a brass 'fishing scale'......I watch......he puts a gallon of a brand on the scale, then another, and another, etc. He chooses a gallon. Naturally, I had to go over and ask what he was doing "weighing the amount of copper in each paint Bob.....this gallon weighs the most and that's the one I am putting on 'Apocalypse', his 40 ft, home made in his back yard, race machine. Maybe that's how I will choose my next gallon of antifouling paint!
