5 diff. people can run the same laptime 5 different ways.
Very good point Robert!
I've had just such an occasion happen at the track (Sears Point), where I was riding a 400'cc machine (Kawi, ZXR-400). My lap times that day were very close to the lap times that another fairly skilled trackday rider was doing, on his Yamaha R1. Upon seeing me on track in one session, he decided to "hook-up" with me from behind (I didn't know at the time he was there).
For the 400'cc machine to be turning similar lap times, the numerical speed at which the ZXR was traveling into..... through......and out of the corners ......... was MUCH higher than what the R1 pilot had been doing while netting those same lap times. The result? Mid-way through the first lap behind me, he tried to navigate into/through/out-of "The Chicane" (the previously used AFM "Turn 12") at the same pace, and found him and the R1 sliding down the pavement.
Later when the events became known to me (I had no idea he was behind me, or had crashed), and we discussed the sequence that had led up to the crash ..... his comments were the following:
1. He'd seen that he was going about the same laptime pace as me, and thought he'd tag along for fun.
2. He realized (after-the-fact) that he had neglected at the time of the incident, to take into consideration the "different ways in which different bikes/riders achieve the same lap times".
He said it'd dawned on him, after he'd gotten up from the crash, that the cornering speeds that the 60HP, 400'cc machine must have been carrying, to do the same lap times as his R1, would have been much greater than the speeds he'd previously done in those same turns ....... hence the crash.
So as Robert so accurately stated .........
There's different ways to achieve a specific laptime around a track. One that's done with smoothness, consistency, and control ........ is the one that I believe should be the goal for all riders to shoot for ..... rather than that "one flying lap" approach that seems to be more and more prevalent lately at trackdays .... where on-board lap timers abound on even "C" Group rider's bikes!
