If your craft (which requires fuel items to refuel) is at 99% fuel, it will consume a whole fuel item to get to 100%. I know, it's a minor thing. But in some rare cases, the fuel items can be rare or expensive. It's possible to micromanage refuelling by only buying/moving the fuel items to the craft's base when the whole fuel item is consumed, but it's inconvenient. Therefore, implementing something similar to statistical bullet conservation would be useful.
