Hi,
I’m not good at English, the last sentence " If there is bad data, the previous score is used, but there is always an average of channels." make me confuse.
is that mean the average would reduce the influence of bad data ?
Thanks!

“Note that it will take approximately 1 minute with Muse on the head before these values will start producing something relevant. These values are emitted at 10Hz. Each channel is scored independently for alpha/gamma for mellow/concentration, and the average of the two channels is taken every time. If there is bad data, the previous score is used, but there is always an average of channels.”
