Not an objection, so much, but would .2c and .18c work for what you need it to work for in story? That would let us set the flat canonical max for speed drives at .2, which somehow feels more right to me, given Catty's issue.
If that's carving it too close, though, then as I said, I have no real objection to .25/.2
