I'd have to have someone standing next to me while doing it to time it, sadly I don't have anyone to do it... though I am looking for a way to record video from the ps3 so I can show people how I do what I do, well it may not be a "how" but at least showing them that I do it. Gonna try a run right now and try to time this in my head, only option I can think of.

Eh it's around 10-11 seconds or so to complete a lap at 90-91 ish. Sorry for not having a solid time, but I don't have someone next to me with a stopwatch at those speeds, though I'm fairly certain I was counting correctly in my head.
