I just checked this out.

We do what Opera and WebKit do, namely switch at the 2 second
point (mid-point) of the discrete to animation. Also, we ignore
the keyTimes so the change happens at 4s instead of 2s for Cameron's
last test case in 92-t.

This is just another data point for you, I don't claim it's
what SMIL expects...

Cheers,
Alex
