Was just looking at the accel vs speed list you have there, and I have to say it feels a bit unbalanced to me. In particular, if the whole point of accel drives is to make those long hauls in short order, then having the Sun/Limit run be the exact same amount of time means that, well, there really isn't any good reason to have an accel drive. The only time it would be really worthwhile would be if you happened to have to go from an outer planet on one side of the sun to an outer planet on the other side of the sun, and even there you could just head to the limit, warp drive the circumfrence and head back in again. In the meantime, you're much worse off for the little "tooling around the inner system" runs that people tend to want to make a lot of.
Caveat the first: this is off of the .1c speed drive limit, and accel drives don't have the same sort of size factor (though accelerating a large thing will obviously require more engine than accelerating a small thing). Essentially, then (if my understanding is right) accel drives would still work well for large ships moving medium-to-long distances but not for anything small enough to pull .1c itself.
Caveat the second: This entire structure ignores slingshotting, which is significant but not always available.
Caveat the third: some folks might have accel drives anyway because that's what they got, or because they just don't cae but so much about speed.
Still, even with those caveats, I think it's something to consider.
