Here's my sort-of different take on the phrase "world record": There are, as stated above and we all know it anyway, a few organizations that certify speeds attempts and reward the fast ones with a "record". Let's assume that you have one (or more) of those records in your class, and so now you've got a record that at least has been certified, no matter which group certified it.
Stipulate, for the sake of this discussion, that the FIM record speed in your class is 165 mph, the SCTA record speed in your class is 170, the ECTA record speed in the class is 175, the El Mirage record speed is 168, the Muroc record speed is 160, the DLRA record speed is 171, and so on if I've missed any sanctioning group. Each of those speeds is a record, right?
Which is REALLY the world record? If you ask me -- the fastest speed is the fastest record, and therefore really is the world record speed. Sure you can attribute faster/slower speeds to track, conditions, day of the week, phase of the moon -- but if you've run the fastest number you can defensibly claim to have the fastest record in the world, and therefore the world record. Ergo, the ECTA record is the world record in my example.
Okay, folks, now it's your turn.
