Confused

Played the Derby course today at the Belfry, shot 99 gross nett level par but despite adding my stableford points time and time again I only got 35 points.

Can anyone explain why?

How thick am I, yellow tees are par 70 so +1 would make 35..

That's what happens when you stay up all night working and go straight to the course...par 71 for the red tees...doh
