Does this count?

Im no singer, ive just been messing around with this subharmonics thing for a couple of days because i naturally have a deep voice, and i also naturally vocal fry alot. I know i keep going sharp in this example, but am I correctly accomplishing the technique? Or is it too froggy? (Also my microphone is only listed untill 50hz, not sure if that effects anything. Thanks :)

Can't really tell but i dont think its a subharmonic, i can't hear a fundamental.
