Yeah, this run is nothing special. I'm pretty sure there are other routes to unlock the GPs faster but I did this run just for fun (and for the free WR TriHard) and I wasted a lot of minutes because some shit happened during the run (yeah, related to the earthquake but whatever), also I had to do lots of retries and I ended up taking a while to do the Super segment.
Since no rule has ever been specified, I followed the ones that have been defined for Burnout 3, so I made it like this: -Start the timer as soon as you select the car for your first event (I restarted from the first race because I forgot to turn off the takedown camera...then I failed in doing it (I pressed Triangle instead of X to apply changes) and I didn't want to reset again so I turned it off during the run, not like a 10 seconds time loss would change something anyway...) -Stop the timer as soon as you cross the finish line in the Super GP
I hope it's ok.
(Little note: commentary may seem out of sync because I streamed the run through my PVR (yes, I own a PSP-2004 and the component cable so that it allows me to connect it to the Hauppauge PVR), which has 1 second delay. I added that delay to livesplit to avoid confusion and don't make it look like early splits/late splits whatsoever, but I forgot to do the same with the mic, it seems. Not a big deal anyways).
