A 'win' refers to a run where this $\lambda$ scored the highest correlation.\\ For EMG there is no clear preference but it seems like 100 should work as parameter. For EEG we see a clear preference for $\lambda=100$. Low Frequencies seem to prefer a lower parameter of about 10 however this was only evaluated for one session.
