Here's my go at adding some additional love for Pilots. This will decrease fuel usage with more experience. I have tested that the extra delta-V does not show up on KER or MJ, so you will have to do the maths in your head, etc.... So without affecting Thrust or Specific Impulse, this reduces the fuel flow and increases delta-v by up to 15% for fully experienced pilots.

{
%EFFECT[FuelUsage]
{
%modifiers = 0.99, 0.97, 0.94, 0.90, 0.85
}
}
It seems balanced but if you think it is OP, adjust the numbers accordingly.
