Slash Away During Frenzy Time!

I saw a post about sharing strategy info, so here's one. How many attacks were you able to land during Frenzy Time? I counted each time the character slashed as one attack, and I managed to get a maximum of 11 attacks in a single Frenzy Time. I wasn't intentionally trying to make it short; Tō holds down a demon, draws a circle, passes through the center, and releases, repeating this process.
