That one got away from me but I guess it was telling me 4 in a row was enough.
That great battle in the first stint played tricks on my mind and I miscalculated on the fill-up. "Oh I used less than 1/2 a tank, I can just go right above half and I'll be fine". Yeah, sure you will.
Went into fuel saving mode for a bit but caught lap traffic going into Eau Rouge which cost me about 1.5 seconds of my 2.3 second lead. My fuel saving gap was now gone and it just went downhill from there. If I still had ~2 seconds to use for fuel saving I may have just barely made it. Had to pit with one lap to go with .5 laps of fuel remaining.
