I think this falls into the stupid rules arena (better than my previous anecdote), but not as a funny stupid rule.
From another thread here:

The rumor is that a proposal was made to reduce the allowable Fz load value (upper neck tension) from 3,000N to 2,500N. This would "decertify" the Leatt brace, which was "certified" in late October. [/b]
A 60 day certification? THAT'S STUPID.

Or politics as usual. Oh, I forgot, Gary said no politics involved.
