Table 1.

Optimizing accuracy and information transfer rate.

Flash duration (s)	Flash sequences	Accuracy (%)	Bit rate (bits/min)
1/64	1	42
2/64	1	61
3/64	1	81
3/64	1	78	53
3/64	2	92	60
3/64	3	98	56

The first three rows of the table show the relationship between flash duration and classification accuracy with a single-flash sequence. The lower three rows show the relationship between the number of flash sequences and classification accuracy using a flash duration of 3/64 s (i.e., 47 ms). The data in these tables corresponds to the traces in Figure 4.
