Just my 2 cents, based on personal experience.
I too, have been victim of this very same issue... difference being, I didn't learn after the first time it happened. Took two more incidents... which is why I haven't been on a track for almost 6 years.
in short
After providing my lobe number to my Comp Cams rep... his response:
"YOU CAN'T REV THAT LOBE" !
me:
"THAT'S WHAT I'VE BEEN TRYING TO TELL YOU" !

Yes, there ARE lobes that can't be controlled at RPM... "torque lobes", as they were described to me.
