Yep, you do. And you're still Level 2. More experience at Level 2 may well have resulted in a greater chance of success on the Level 3.
It's not a guarantee, but it helps the odds.
Now, before anyone asks, I'll be up front on my Level 3.
Attempt #1: LDRS 21, HyperTEK hybrid, the ignition wire induced a current in the break wire I used for launch detect, confusing the altimeter and causing it to fire pretty much as soon as the wire broke. Someone else had the same failure at the same launch, and the rocketry community learned from it.
Attempt #2: Same rocket, same motor, different electronics setup. Nominal flight, but the main came out at apogee, and Tripoli rules at the same said "recovery as designed". I didn't plan for a main at apogee, so no cert.
Attempt #3: Same rocket, same motor, several years later. The airframe collapsed on the way up. The suspicion is that in moving the rocket around over the years, I whacked it with something and compromised the tube (fiberglass over cardboard).
Attempt #4: Up was fine. No recovery on the way down. Lots of theories as to why, but nothing concrete, because we couldn't get to the charges.
Attempt #5: The infamous buckets. Worked nominally, all was fine. Three weeks later, I flew another rocket, at BALLS, on a Research M to a smidge over Mach, with nominal recovery.
