What I have noticed is a lot of the guides tell you to filter by this when doing long exploration, but won't you be missing out on lots of systems? Surely you don't need to fuel scoop *every* jump? Is there a tutorial for exploration which explains a better way?
You don't miss out any if you use economical route plotting, but you will then be doing a lot of jumps to get where you want to go.
Also the kgbfoam filter doesn't have to filter your route, it can just show you the scoopable stars. Unless you have the filter route option ticked, it won't actually affect the route plotting.
If you find yourself in a brown dwarf field and getting low on fuel you can just do this to easily see a nearby scoopable.
There are lots of explorer videos about but, to be honest, if exploring, and you are at a scoopable, it makes sense to just fill up while there.
The max jump range is only really important if you have a fixed destination you want to get to asap. Otherwise, exploring is best done at a nice easy pace. Less accidental bumping into stars that way too!
