After much delay- my venture into winging finally began!!!

I am 2 sessions in. I am 90 kg on a 6'x27" 108L SUP, 6.0 Wasp. The first day was a pretty tough setup to learn. 20 kts direct onshore in a shallow, tight cove, very tight, steep bumps. I couldn't point high enough to clear the point on either side, so- lots of short slogs off foil and paddling upwind dragging a wing. I did get my knee start on my good side somewhat sorted. Knee starts on my switch side I burried the tip most times. Progress though.

Second day.
My buddy 2 months into winging drops me solo on the bay and heads to the surf side of our location. Not an ideal setup, but a bit easier to learn on: gusty 15-25kts slightly side/off-shore winds. Calm water. First go- I knee started on strong side, slogged along a bit- reached wind-line, pointed downwind, pumped board/wing... teased with getting on foil but... no. Starting to get blown offshore- I aborted- long paddle back to shore. Rest.
Second go: Decent knee start, slogged along off foil, hit wind-line, pointed downwind pumped, pumped, pumped.... up on foil!!! So stoked! Could now pinch into wind- did so a bit, got inside- lost wind, off foil... did a low plodding "jibe" to topside. could at best beam reach to slightly downwind off foil on toes side. Couldn't get on foil. One near miss on a good gust. After being blown offshore too far- another long paddle back in. I repeated the same pattern into exhaustion. My knee starts switch stance are pathetic. Once up switch stance- not close to getting on foil. Or... off foil jibes to toe-side keep leave me unable to get on foil. No on-foil jibes yet.

I suspect a more stable board would help me out learning on my bad side. As would downwind runs rather than short runs followed by tiring paddles. Other than progressing my strong side to the point I can jibe strong heel side to toes side- how on earth do I get on foil/work on sailing on foil on my weak side? Are most of you pumping up to foil switch stance, pumping up heel-side, getting up strong side, jibing to toes side? I know more than anything repetition, taking my lumps is the answer, but any suggestion on approach would be appreciated.
