Hey Chris,
yes, I agree, absolutely. That’s why I wrote this and this to help people to understand what the values on the control page mean and how you can enter them to (re-)create a certain machine state.
By the way, I found out here the other day that the offset values are not lost after a power outage or a machine shutdown. I found that they are recorded in the bbctrl log file and this file is still there after reboots or power outages, in fact it lives as long as the logrotate configuration lets them live, which is rather long.
