Methinks I tend to have random bursts of kick-ass-ness. I'll usually go 2-3 minutes or so without fragging many people. Then I'll have many kills in succession for a little bit, and the process repeats itself.
As for the rail/sniper...
Bleh, I suck so bad with those weapons. Insta-hit or hit-scan-like weapons are my downfall. Try as I might, I think it's going to take several more years for me to actually be decent with them.
That aside, I think I excel with projectiles, especially ones that travel in an arc. I'm just much better at predicting where they're going to end up.
Anyway, my point is GGs everyone, and for all of you who are trying to improve your game, you picked one hell of a group to practice with.
