Hi Russel,
Had a chance to test pretty extensively, and it appears that's a good assessment. Answers below:
1) Confirmed, bug is audible 90% of the time, regardless of time taken between preset changes.
2) Confirmed. 5 second timeframe seems close, if anything with a slight increased window (up to about 7 sec max) for bug to occur. Waiting longer than that seems to prevent bug from happening.
Hope this helps, please let me know what else I can do, and thank you again for efforts to try and correct. Cheers,
Chad
