Not terribly worried, but my results are dropping

I got my Muse for my birthday in May & have used it EVERY day since then. Absolutely love it. HOWEVER, I’ve been on vaca the last two weeks, ans afterr a personal record 191 “birds” one day last week in a 20 min. session) my resultrs have really dropped: significant increase in active and neutral. Any suggestions on methods I can use to drive up my results (I normally do an exaggerated breath in and out so that the sound will dominate my attention). Thanks in advance for any help & glad to be part of this community.
