Fair point if we only consider the vanilla roboports, but this mod is designed to support mods that tweak or add new roboports too, and that wouldn't work with absolute values.
Ahh, okay that works.
I've used your mod to make a "city block" blueprint by tweaking the roboport range to 1.28x
Turns the range of 50 into 64.
This allows the range of roboports to line up with the maximum range of the big power poles. Vanilla ranges don't play well together, so I really appreciate this mod, thanks.
