It's been several years since I played this game, so not sure if I can help you with categories, but for the timing, I think the timer should stop when you finish the last race or when the game shows you that you've completed the game like in U2.
I've added ProStreet to NFS series and made you a mod, so you can edit the categories as you like.
You could add difficulty variable like I did in U2, at least as additional info.
Don't expect too much competition in NFS careers. It's a pretty new speedrunning territory and there are basically no glitches/shortcuts, so improving a run will usually require better driving skills and nearly perfect execution in all races, which is really hard in such long speedruns. I think it's more likely we will see competition in IL category.
I might attempt PS in future, but my priorities are currently different - U2, finish HP and then HS career
Well, I meant glitches useful for a speedrun, not glitches like ECU glitch in U2 or OoB in PSX version of NFSIII :)
What's the glitch for PS? Could you write a guide? That would be very helpful. I'll do the same for U2 when I have more time.
