How fast does the decision tree output a decision? Looking to the videos it seems at least that we need 1 to 2 seconds of input signal.

The latency in the MLC outputs depends on the selected data rate (MLC ODR) and on the window used for features computation (expressed as number of samples). 

Considering these two parameters, the equivalent time will be: window_length / MLC_ODR.
