MuteDeck is on a continuous loop to detect and find the status of Zoom. To balance the resources the software needs (CPU usage) and performance, we've put this loop on a 1-second delay. So, every second the call status gets updated, which can seem like a delay when you're paying attention to the buttons. We've found that this design is the sweet spot and is the best balance.
This may change in the future, but we want to be absolutely sure that the software does not interfere with your computer's resources and has a very small footprint.
