That's happened to me too, still does, but for me it's only ever good for "great" laps, not "pbs"-
I think it comes down to how many laps you've done on a track and how close you are to your tpb. Once you have a lap which is very close to all your best splits combined after many hundred or thousand laps I don't think you'll get any faster by going on autopilot - then it's really looking for those hundredths with everything you've got.
However, one thing that's happened to me a few times lately is that on a bad first split, last lap, with nothing to lose I go flat out and get a fantastic second split. On the contrary to a great first split and it's all "oh no, too fast, must get pb now, this is the chance of a lifetime ... doh" ...and you just overdrive and overpush and don't get anywhere at all...
