From memory, I remember thinking that the rev match was initiating way faster on the gt3 (seems to flare revs just by touching the clutch) but then I'd try to row down through the gears quickly without letting out the clutch (6543) for example.. and it was strangely a lot slower than the spyder.

With the spyder it was more intuitive.. it would only flare revs (rev match) once I was already going towards a defined gate in the transmission, and then I could just keep the clutch in and bang down through 2-3 gears and hear it go "vroom-vroom-vroom" in quick succession.. with gt3 doesn't happen. It's definitely feels like a different setup. Not bad.. but spyder was more intuitive.
So it's not just me... Our GT4 and 981 Spyder operate the same way, just like Calexico describes, and the GT3 is doing something differently. I'll have to get more seat time to try and figure it out. I also have an AiM setup for both cars so maybe I can get some data. TPS should be zero I would think even with the engine rev matching during these downshifts.
