Crosscountry,
The leagues that use it here are our area's stronger public school leagues. Our shot clock operator pool is pretty strong out here. Most of the experienced ones go thru at least half a season without a CE involving the clock. The most common one I've seen is inadvertent reset but they're able to correct pretty quickly using recall or they happened to catch a glance of where it was at prior to reset.
