Is the final jump range going to be 72.5?
you have to come up with what you understand with laden jumprange.
or you look at your current AspE build and add 15%.
to achieve "final jumprange" you'll take your current "final jumprange" and multiply by 1.15 .
e.g. my main accounts dbe has a max jumprange from 71.90, a unladen jumprange (without cargo, but fully fueled) of 66.98, and a laden jumprange (with cargo and fuel) of 66,65.
multiplying each of that numbers with 1.15 (as that one is nowhere near to get a new FSD, so will have an old one for some time) gives 82.69 - 77.03 - 76.65.
what your ships plotted jumprange is going to be, nobody knows without knowing your build, size of your fueltank, how many limpets or probes you might carrying etc.
