High power? I've launched maybe 20 flights, only 1 had damage, my first L1 attempt I zippered the tube and the nose cone came off. Only one other launch where something went wrong and my DD screech only deployed the drogue, though it landed in a freshly plowed field and was fine, not even a paint scratch.
Low power, probably 10-20 percent, mostly repeat offenders like the Estes Renegade D(Oddly shaped), Estes D region Tomahawk (Beat up with F composite motors), or my Estes Baby Bertha (30+ flights, 20+ on C motors another 5 on D motors, first rocket, badly made) and some low power scratch built rockets that weren't as stable as I thought (It flew fine on B motors! just not C motors)
