I bet your pretty stagnant on the TT too. Your just content with your riding.
Regardless of talent, progression is pretty related to how willing you are to fall. Somedays you get cold, your hungover or its like the 8th day in a row and less than great conditions. Not enough time on the water? Your likely sick of falling after the first 10 min and just wanna fly around a while after that. Everyone gets sick of crashing. Some more than others. Plenty of pretty good kiters almost never bail uncontrollably on a TT or surfboard. I bet many are less than stoked to fall in every transition again, but progress comes from trying stuff you can't do. By definition, you have to accept that your likely gonna crash. Eventually you wobble through one and boom, you have the blue print with a side of motivation. As soon as you can pull off 10 straight you gotta dive into the next thing. Fresh success begets more with foiling. ie. A lot of transitions (which is likely most of what were talking about) is tempo and kite mechanics. As soon as I figured out heel side tacks one way, I attempted it toe side the other. Significantly different body positions, but managed to nail the second one simply by having the tempo and kite choreography freshly ingrained. I'll stagnate soon enough on foil, but so far I'm still willing to fall a whole bunch of times in a row, even if I don't have to.
There is a shit load of crashing in the early stages of foiling and I totally get that once you can ride around dry for a while, many will prefer to stay that way.
Whatever, once you reach the stage where you can go out and stay dry, you gotta convince yourself to get wet. Over and over and over. At this stage I pick my moments for skill work. When I'm fresh, warm, its flatter, etc. Usually only give it a good 10-20 attempts then change gears and just ride around awhile. If it went well, go back to it after a bit. Super rewarding to drop a fresh move into the flow.
Waves are a distraction. There is a big enough learning curve just learning to ride them. They can keep you playing it safe in transitions.
