Holy moly, that's a lot of flaming. haha...
I bought a lap timer a few years ago because I wasn't riding with any close friends at the track and needed something to keep me motivated. Also I wanted to know if I'd be wasting my time if I decided to try racing. Now that a bunch of friends got into track riding it's a lot more fun, regardless of times, but I'm still trying to improve my times. On a very technical track like SMP Long it's good to break the track down into sections and try different lines per session to see how it affects your times. Sometimes a lap that felt fast may not be fast, and vice versa.
Anyway, last year I did a 1:22.6 at TMP on my SV650. The session where I did this I was dropping my lap time by about 0.3 per lap (I had lots of room, no traffic, for maybe 6 laps in a row). I got down to a 1:59.9 on SMP Long also. Same thing, each lap was about 0.3 lower than the one before, so I knew I was heading in the right direction with my choices that session.
