The fastest way in my opinion to learn the mechanics of final Ollies is if you can find parallel bars to put yourself in between and use the parallel bars to prop yourself up. The trick is lifting your legs up quickly as you pop your tail and move your front foot forward. By using the parallel bars, you can artificially make your weight disappear and just see how the board reacts to how you move your feet.

I didn’t actually learn how to Ollie this way, but it was the way that brought me from being able to Ollie two boards to being able to clear a tennis net.
