Upon further reading, the feedback I'm getting is mostly correct - the manual does say to add the wind speed to your landing speed in "strong winds", although it doesn't define "strong winds". Interestingly, though, it recommends calculating a landing speed based on best lift/drag ratio, not stall speed - that's something I've never encountered before.
Best L/D is about 52mph dual, and 46mph solo, if I'm reading the performance curves right. That's enough to make a bit of a difference, whereas the stall speed only differs by about 2mph dual vs. solo.

Vstall for the the 2-33 is 35 mph
The PoH tells me it's actually 31mph solo, or 33mph dual (which then will obviously depend on the exact weights of the occupants). 35 vs 33 wouldn't make much difference to me, but 35 vs 31 would. It would mean flaring at 50 instead of 55, if I base my touchdown speed on stall speed.

The approach speed should be stall plus a half, plus 1/3 of the wind. So 51 no wind, 55 at 12 mph, 60 at 27 mph and so on. Do the calculation on the ground before you launch, so if you run out of time on downwind to calculate, you have the speed ready. Our approach speed is designed for safety, control, and also gives us maximum penetration into a headwind. You can use the same speed for flying upwind, keeping in mind that the upper winds are higher than on the ground.
The last landing you made, Ken was with NO headwind, so your ground speed was higher. If you flare with about 1/3 - 1/2 spoilers and get the nose up during the actual landing, your airspeed and ground speed will be less than approach speed, quite close to what the book says. But be sure to keep the approach speed until the flare.
Sorry for repeating, but the PoH tells me to base my landing speed on best L/D, not on stall speed. That is contrary to every other plane I've ever flown, but hey - that's what the people who designed, built, and tested the airplane say... so who am I to argue with that?
If I land at best L/D solo, that's 45mph. If I assume a 10kt headwind, then, yes, it's 55 (ignoring the mph to kts conversion). If I do that dual, that's, let's say, 50mph dual with no wind, plus the wind factor. 55 makes sense in that case.
So yeah, I still think that 55 is a bit fast to land these boats solo, barring at least a 20km/h headwind.
It's entirely possible though that flaring at 55 with no wind, solo, is
too fast, because it assumes a wind correction that I haven't needed to apply on my more recent landings. But it's not just my groundspeed that feels too fast at 55 - my airspeed feels a bit too fast, the controls feel a little tight to be landing with, etcetera... sorry, it's hard to communicate this effectively.
