This topic came up in another thread. Here: https://photography-on-the.net …showthread.php?p=17522880
I suggested that most Canon shooter's likely leave this option on AUTO-ENABLED, whether they do periodic manual cleaning, or not. I thought it might be interesting to put some numbers to this. For the record, I leave mine in AUTO-ENABLED, all the time, and only do a "Clean Now" to map out hot/dead pixels.
EDIT: Just noticed I messed up the poll choices. Default is actually ENABLED, not both. DUH!
Enable (default)
