Rate of produced regimes (Eq. (19)) for written low B♯ fingering. Green: first register, red: second register, blue: quasi-periodic. Linestyles indicate the characteristic time. Dotted: τ_g = 0.1 ms, dash-dot: τ_g = 3.2 ms, dashed: τ_g = 100 ms, solid: averaged rate. An upward triangle marks the maximum first register averaged rate, a downward triangle marks the minimum second register rate.
