Does running a proprietary system rule out competition and restrict you to recreation? I have no idea what the FIFA-equivalents is for bowling, but I imagine there is one, and I imagine that it has a list of rules for lanes to qualify as competition venues, including scoring systems from approved vendors, etc.

Not sure if any of that's relevant to you!

Yep, USBC. You're exactly right, they do have pretty precise requirements for sanctioned league play. But casual 'open' bowlers don't care about that stuff for the most part. So if we're not running a league, we can flip back and forth and run the two systems in parallel (less maintenance on my very-expensive-sanctioned gear at the very least)
