The 'other' possibility I had considered is that the threshold are interlaced between compounds: D1, W1, D2, W2... Although I would expect the values for the first two threshold to be closer to each other. It sounds more and more like the extra entries are simply ignored. Which makes me wonder why they exist in the first place? (Copy paste error from a basic cockpit, perhaps?)
I think it's just because 6 is the maximum number of speed anims per graphical compound, so 5 transitions is the most you need. I wouldn't be surprised if specifying fewer still worked, but leaving the extras won't hurt.
