The only problem for me is the acceleration maneuver, you are going from speed 0 to speed 1 but without moving at all ??
I can't imagine any good explanation...
scenario:
You kiss your wife cause you have to go. You kick off the jetpack thrusters.
First round you accelerate from 0 to 1 and that's it cause your jetpack has only 1 system strain left
Round 2 : seconds laters your jetpack is over 100 decibels, at speed 1 but you didn't move a centimeter yet !! now you use that maneuver to actually move ... your wife is now deaf !
strange...
1) Your speed being 0 doesn't mean you're not moving. It only means that your movement is, on a planetary scale, so negligibly slow you can't change rangebands within a round or two.
2) I've only been paraphrasing RAW on starship and vehicle movement. Don't blame me!
3) The length of a round is not fixed; "[it] can last for roughly a minute [...]".
4) There will always be inconsistencies, when you quantise time at a macroscopic level.
