What drove me to make this poll was the Rebels episode Shroud of Darkness. In it, we saw a hologram recording of Anakin demonstrating his adjustments to the Form IV lightsaber technique to be effective against ranged attacks. Ezra Bridger even states that he watched the recordings to further his own lightsaber training.
Though, I personally think it would’ve been more interesting if Anakin recorded himself demonstrating the stances and maneuvers of his mastery of Form V as opposed to Form IV.
