Re: "fast-dock tech that will reduce coupling time to just six hours."
Based on my experience*, it works as follows:
Launch spacecraft, try to launch directly into an intercepting orbit.
After several minutes realise that this is most certainly not an intercepting orbit, even if I leave it for several months.
Swear profusely after looking up orbital mechanics and discovering inclination changes should be performed before circularisation.
Match orbital inclination, wasting lots of fuel.
Check target location and relative orbital average speeds.
If ahead of target and travelling faster, or behind target and travelling slower, wait.
Otherwise, burn prograde to increase orbital speed to let target catch up, or burn retrograde to reduce orbital speed to catch up to target (yes, really), wait.
Grossly overshoot/undershoot, swear profusely, repeat above steps but with less difference in spacecraft/target speeds.
After many orbits and adjustment burns, approach target while travelling at approximately the same orbital velocity (i.e. pretty much same direction/speed).
Start moving slowly towards target, preferably using only RCS (if this was even remembered and set up correctly during spacecraft design/build).
Get impatient, increase speed.
Panic when realising closing speed is too high.
If lucky, overshoot, repeat last three steps. If unlucky, decide to use main engines to slow down, grossly mismatch orbital velocities, repeat last ten steps. If unluckier, expose target to close range 100% power rocket exhaust while trying to slow down, destroy/damage target, mission failed. Or, simply, collide with target, spacecraft/target damaged/destroyed, mission failed.
If exceptionally lucky, achieve holding position within tens of metres of target, negligible relative speed.
Swear profusely when realising target's docking port is on the other side.
Set up spacecraft controls relative to docking port, target other docking port.
Try to remember all RCS translation/rotation controls, hope spacecraft CofG is where it should be.
Move slowly toward target.
Wait for ports to engage, if they're too far away, or at an angle, back off and try again.
