I had the misfortune to play with this chap during the L4D/2 vintage years and all I can say is he talks the talk but the walk is definately no where to be seen. I don't think I've played much BC2 with Hyperst (maybe the odd game) but I think I know who I believe.
believe what??
The screenshots are there to see.
I had a better score than both of them its plain to see, and ive never played L4D with you.
