YEP. I know that.

But a ship with 6 engines uses 60 supply points/sector (normal engines) and a ship with only 3 engines only 30 points.

ex.: a fleet of two ships (1x 6 engines, 1x 3 engines) will move only 3 sectors/turn.
The first ship uses 180 (6x10x3) supply points and ships no. two only 90 (3x10x3) points for a total of 270 points.
This small fleet uses 90 supply points/sector (max. 3 sectors/turn).

Say that fleet has a total of 4500 supply points:
it has a max. range (full supply) of 50 sectors and will need ~17 rounds to move the max range.
(all without any better tech!)

A fleet of 2 ships (6 engines) and also 4500 supply points:
That fleet uses 120 supply/sector - max range of ~37 sectors but will need only ~7 rounds to reach it!

That can be very complicated when there are much more ships.

I will find it usefull to know the range my fleet/ship can move with the current supply points.
A small number in brackets behind the supply points will be good.
-> Supply: 2450/3000 (26)
