Some recently posted the same question which turned into a mess no one accually answered. I on the other am curious of the answer too. Part of the debate was what he ment by how fast and how to measure it so hows this.( O and plz only serious answers this time and none of this speed don't matter replies or other useless replies because thats not what im asking.) What is the fastest pace you can play 16th notes evenly for at least 30 seconds (since your arm does wear down we need a minimun time you can keep it up) if playing just a single solitary note over and over. Plz answer in beats per minutes. Optional: Include your right hand fingering method you used?
