First, I am finally starting to get a good paddle down that works for me, the most impactful tips I've learned are to keep your elbows up on the upstroke, but dig deep down on the downstroke. This keeps my forearm as vertical and deep as possible through the stroke, which maximizes the actual thrust I feel I get on each paddle (I got the verticality tip from a Rob Case video.)
Now to timing. As a beginner I think we tend to start further outside to avoid getting caught inside, which means paddling early to get to a good takeoff point and also generate speed since the wave face is usually much less than 45 degrees. Being on a bigger board helps enable this as well.
But I think that approach messed up my timing on more critical and bigger waves. What I was doing was paddling hard early, then relaxing when I saw/felt the wave catch me thinking okay, now the wave will take over. Feeling the water under me being sucked up the face probably gave me the impression that I was starting to go down the wave, when I actually was not quite there yet. So I'd try to pop up, but basically no dice- worst case I'd get sucked up and go over the falls, best case I'd manage a sloppy drop in but end up behind the shoulder. My beginner perception was that on a bigger/faster/steeper wave I have less time and need to pop up sooner, and acting on that perception really worked against me. Popping up sooner is fine, IF you have actually finished paddling into the wave.
So what I do now is the opposite- give a couple of paddles to start moving before the wave reaches me, but then paddle hard right when as the wave is reaching me (I have developed the positive habit of looking back and not just relying on feeling the wave.) This is the time where the extra paddle effort keeps you from getting sucked into the falls, and really gets you started going down the face. I don't stop immediately either, I 'paddle through' until I look and have a good sense of where I'm going to try to go on the wave- at this point it feels like an extra 2 paddles is better than not enough paddles.
Doing this has enabled me to start further inside, because I'm much less afraid of pearling or going over the falls. And since the wave angle is steeper, my hit rate is much higher. Instead of paddling to try to catch the wave, it feels more like paddling to get ahead of it, and then drop right in.


The thing I'm trying to work on now (well one of the things), is to look and have a plan of where I'm going to go, before I pop up. Seems painfully obvious

As beginners we try to soak up as much information as possible, but there is still a step where you have to learn how to subjectively recognize when and how to apply different tips/lessons.
