I honestly wouldn't have looked it up, but you posted a 0% humidity for your record run. There'* no such thing, so I wanted to start with the actual humidity of that run .
That'* when I found that it wasn't 45-50° as you claimed, but 80°, and instead of no humidity, it was actually 74%.
I'd say based on all the above information, and the fact that the 95 octane did nothing to improve your performance, and may have actually hurt it, your timeslip is major bunko.
Just my opinion, and I'm still crunching data.
