Recovery charge delay was lughtly drilled for long 10 sec delay (10.5 sec was the intent).  Full deployment charge (1.4 g) was loaded. 

I failed to account for the concurrent burn of propellant and delay grain.  Delay should have be 11.5 sec. 

Rocket launched normally.  LP-36 chute deployed pre-apogee at high speed. 

Rocket returned to Earth at a high descent rate (~8.5 m/s) landing safetly in the recovery field only twenty feet from the launch pad. 

Rocket was presented for post-flight inspection with a repairable 2.5" zipper on booster section and deemed readily repairable for a turnaround flight. 

Level-1 Certification was awarded.
