Now that I don't have a target on my back and the XIV's to waste in the game. I found that when you get enough fuel burnt out you start flying like a spit8. Then it's time to RTB bingo fuel. I hope it's just a fad that will pass but, it also seems like at the moment every jackwad in a spit16 needs to single your XIV out from the crowd and prove you ain't chit. And you ain't if you have much of a fuel load.
Try taking it out with 100% and the slipper tank. Burn the wing tanks first. Then the rest of the way to the furball on the slipper tank. At which point put on an egg timer for 8 minutes and watch the fuel gauge swing from right to left before your eyes. The performance report recommended the 90gal slipper tank to give the XIV similar range to the spit8.
