How are you sure that the perceived improvement is due to the n-back and not that you only do n-back on days with abnormally good cognition? Like if you slept very little you obviously wouldn't not perform well nor do the n-back.

Tbh I use the dual n-back protocol most vigorously on days where I feel cognitively sluggish as it's benefits are most apparent to me then.
