idea being (this is for a multi room audio switcher) that the same status updates can be displayed in a remote area as well as on the front panel without having to write a 2nd round of code just for the front panel.
How much time are you trying to optimize? As it is for a display (human reader) timing cannot be that critical I assume or ...
You can optimize the send communication by only send info when the numbers have actually changed.
You need to buffer the state of the remote display for that of course.
