fat ass RO can't even keep up, without shooting?
Wow yeah, that guy certainly was fat.
Anyway, I can assure you that my ass is not fat, and I consider myself fairly fast on my feet in this sport. However I'd likely have great difficulty keeping up with Eric Grauffel even if he was doing exactly what I expected. It would be a thrill to try though!
Anyway, it's pretty obvious that you don't think you need the durability of a dedicated shot timer. Perhaps the iPhone shot timer app would suit your needs instead? For the rest of us...
