The thing I saw was that you are waaaay to slow in getting the kite up.
Just bear off, point the boat in the direction a little lower then you really want to go under spi. Lay the tiller on the back of the boat or throw it in the water sometime during this setup phase. The get on your knees (the boat will track) and hoist that spi with both hands and large arm movements, going from all the way front to almost all the way to the back of you. Rotate your upper body at the hips. Imagine that you are being a grinding on those Americas Cup boats. GO GO GO !
When it is up the boat will have rounded up a little and you should be on course to power up.
Also I thought your mainsail was a little bit to far out (twisted) when you started hoisting your kite. The conditions appeared to be light and so there is no need to depower the boat that much after you have beared off to a deep broad reach. So sheeting out, rounding mark, sheet in, hoist kite.
I echo Greg Goodall when it comes down to spinnakers. Each second lost in hoisting that kite and getting it to drive costs you 10 mtrs. If you are 5 seconds slow then you've lost 50 mtrs and you really have got to be able to tune your rig very well to win those back. So the simple solution is to keep what you got and just get that kite up quickly and driving.
In a crowded mark rounding (not the case this time) you'll want to approach the mark wide and exit the turn around the bout tight. So in wide, out tight. That is tactically better and when you get a shift or alot of dirty air then you won't be put onto the mark. Additionally, when singlehanding a F16 then you often want to be below the other spi boats as singlehanded with spi you tend to drive a couple of degrees lower then the doublehanded spi boats.
The part when sailing under spi looks perfect to me. You know best what the conditions were. If you force me to say anything about this part then I would say, sheet the main in a little more and go to the trapeze. The water is flat so no trouble standing firm under spi. You are light and seems to have sufficient apparent wind to keep flying and the Taipan hulls don't suffer to much when the luff hull dips in now and then (like the Blade does, to these sailors, keep lifting the hull).
