Hi Brian,
I also noticed that the compressor changed the behavior during the last year.
Take a look to the attached plots. In April 2018 the frequency of oscillations is different from October 2018. The time range is 8 hours, one shift.
In April 2019 the compressor is working all the time.
Regards,
Valery
