I aren't that fast tbh. But I can think of 3 combo's where i'm extremely near to the WR.
LX4 on Oval which I did yesterday
PB: 0.52.82
WR: 0.52.02
F08 on oval which was the first time i'd ever got close to a WR. It was ages ago so now I won't be as close to it as I was
PB: 0.36.64
WR: 0.37.29 (That's strange. That would mean I have the WR)
And FOX at KY National REV. One of my best LFS days actually. I was hanging out with the ELR guys and did extremely well. Again, this was a long time ago and I now won't be as close as I was.
PB: 1.55.76
WR: 1.38.27 (Yeah the WR has changed dramatically since then)
As long as you practise even noobs like me can get good times.
