[RocketsNW] Motion: Revise TRA Research Safety Code

TRA Prefects,
I find the 75% rule for research flight altitude limit extremely restrictive towards research flyers. Believe that once an EXer has proven motor design with consistent results, I feel the Prefect should be allowed to waive the rule. LCO/FSO still have final say over flights. But the general rule seems unfair to research. Someone brand new to rocketry has a rocket that sims to the waiver, they are basically allowed to fly because they're using a commercial motor. But someone with a consistent research motor and lots of experience is held back to the 75% rule. Requiring TRA BoD approval seems wrong. The Prefect knows the research flyers in the club, and can make a better judgement.

Do you support this idea? I'll send to TRA if Prefects agree with the recommended change. 
Cheers,
Robert

The Tripoli Rocketry Association Research Safety Code, version 2010 

CURRENT:
Section: 7.5.1
The maximum launch altitude for flights containing research motors shall be 75% of the waiver altitude established for the launch.

Section 7.5.1.1
The BOD may waive this requirement when it can be demonstrated (by past performance, actual thrust curves, etc.) that the performance of the motor(s) to be used shall not exceed the limits of the waiver.

Section 7.5.1.2 
Computer simulations without actual thrust data derived from one or more actual test stand firings shall not satisfy the requirements of 7.8.1.1

RECOMMENDED CHANGE:
Section: 7.5.1
The maximum launch altitude for flights containing research motors shall be 75% of the waiver altitude established for the launch.

Section 7.5.1.1
A registered and active Prefecture may waive this requirement for individuals when it can be demonstrated (by past performance, actual thrust curves, etc.) that the performance of the motor(s) to be used shall not exceed the limits of the waiver. Research flyer must be an active member of Tripoli and certification level of at least 2. 

Section 7.5.1.2
