It would be really nice to have consistent behavior between lines and arcs that way, though I think the limitation is not in the blend arcs themselves. Currently, maximum speed and acceleration are calculated in canon with conservative assumptions. For short arc segments, it should be possible to squeeze a bit more speed / acceleration out. Unfortunately, there isn't a good way to do the same thing with a large arc (like >90 deg). Since the velocity changes direction so much, the overall maximum velocity is more likely to be constrained by axis limits.
One way around this could be to have CAM break up segments into short (20 deg or less) arcs. Unfortunately, to prevent slowdowns, you'd have to keep the segments longer than the minimum length for your feed (approximately 2 * v_max / servo_period). It might be possible to do something like this in canon too, though I'm not sure how hard it would be. ------------------------------------------------------------------------------ Subversion Kills Productivity.
