Time constants (τ) of change in mean and variability of relative phase and intermanual crosstalk.

Participants	Time constant variability of relative phase	R2	Time constant mean relative phase	R2	Time constant intermanual crosstalk	R2
P1	2.2 [1.9–2.8]	0.82	N/A	N/A	6.0 [5.0–7.2]	0.55
P2	4.7 [3.9–5.0]	0.84	5.5 [3.5–12.3]	0.49	6.2 [5.3–7.6]	0.54
P3	2.2 [1.7–3.5]	0.60	4.0 [2.3–14.7]	0.29	7.0 [6.0–8.3]	0.62
P4	1.4 [1.2–1.6]	0.85	N/A	N/A	6.7 [5.9–7.8]	0.67

Time constants for variability and mean were obtained from exponential fits to the variables over the 20 practice sessions: $y(t)=y_0{e}^{-\frac{t}{\tau }}+y_{\infty }$. Time constants for crosstalk were the slope parameters of the linear fits of the log-transformed values: $log\left[y(t)\right]=C-\frac{t}{\tau }$. Values are in units of session; values in parentheses denote the 95% confidence interval of each fit.
