Decided that this would be Spa week, so I don't have to think about doing Spa again after this.
Starting off with the Mclaren, figuring start slow and work up to the faster Gr3. This thing has a very lazy turn in, you really have to start turning well before you might expect. Fortunately, a lot of the usually tricky corners at Spa are easily flat in a Gr4, so missing an apex at Eau Rouge/Raidillon or Blanchimont isn't the end of a lap.
This lap is far from optimum, in later laps I was almost 3 tenths up through S2, but threw it all away at the end of S2/start of S3 and couldn't find that pace again. 158th is decent enough in such a competitive category, so I'll leave this one here.
Tonight, I will tackle the Merc at Spa and see how we go there. I'm expecting that to be even more competitive, so the aim is to be top 500.
I also have the DB11 at Interlagos to do, but will save that for closer to the end of the trial.
