Sure. But why should the game artificially make having to little fuel transfer speed worse then it has to be by having some ships fuel run out down to 0% while your tankers focus on keeping other ships topped up at 100%fuel
It makes no sense...
Steve's changes list seems to make things pretty clear-
"Each tanker class has a minimum fuel setting (in the class window) and will not refuel ships once it falls below that level. Each class & ship has a 'refuel priority', with higher numbers equalling higher priority. The tanker will refuel in descending order of ship priority, then by descending order of class priority. The tanker will automatically move to a second ship (or more) if there is sufficient time and fuel remaining in the sub-pulse."
Isn't this just the same mechanism as for commander assignment? ie, you can set everything as the same priority (with the lowest fueled ship refueled first) or you can get fancy and try to keep your battlecruisers topped up to full even if it means your carrieres run out of fuel and have to stop. Your choice.
