Thus when there are tuning issues, databases often have difficulty characterizing the core issue of tuning. When a tuning issue is noted, the coherence and power values may be "off according to the database, when the real values are not really abnormal, just that they are too slow or too fast.
Theoretically, these issues may prove to be an area where Z-score training may have difficulty, flagging red herrings of power and coherence" though this is an empirical question that will be answered with time and experience
