The thing is, even the UVAST-based distance calculations are a bit of a fraud - the two planets aren't at a given distance, or stationary, relative to one another - to transfer from one orbit to another means knowing where you are in your 'year' relative to the other planet, plus assorted manouvres to make orbit at the other end.
Admittedly, if you can pull 6G continuously this is probably a damn sight easier than working out accelerations for manouvre 'burns' like a NASA astrogator is stuck doing! Ultimately, to some extent you can just point and go....
