I shut down 650 twice a day on weekdays.
There is a certain pattern how I read.
21.30-23.00 or 22.00-23.00---> shutdown--->10h minimum between reading sessions--->
around 09.00/10.00/11.00/12.00 I read 20 minutes--->turn on and leave it in standby--->
around 14.00 I read 30-40 minutes--->shutdown till 21.30--->7-8h between reading sessions.
We will see
