Just because Leafa couldn't discern them doesn't mean that they were going full speed, it only means that they were too fast for her. I highly doubt that they can be as fast at attacking in mid-air as they can be attacking on the ground.

- Eugene has his special armor that can interrupt long combo's with an explosion.

The Japanese version has a か particle in that part of the text which would likely indicate supposition, though seeing as Yen Press ignored it in their version, I'm not sure what to think about it.

Either way, there's no information about how that thing works, aside from the fact that it's capable of pushing the opponent back a bit. And it sure took some time before it was activated. The novel doesn't specify how many times he had hit Eugene by then, but it does seem like over 10 in the anime.
