I look at departure and destination fuel, and tanker acordingly to get the trip cost(down and back) to the minimal cost). Always hated to leave a jet parked overnight fuel of fuel, tires tend to set,(thump thump thump on taxi the next day)wet wings have a higher preponderance to leak...not to mention overall higher landing weights, longer rollouts, and more brake and tire wear...
Why are you tankering fuel? You fly a microsoft flight simulator.
"Preponderance to leak?" Your computer leaks? Wings with fuel tend to leak, do they? Do you simulated airplanes have holes in the wings?
