One of our locations has ninety pins. Maybe of sixty them work well enough to be considered for competition and EVERY week some of them have an issue and have to be swapped out.
Another location has about eighteen. At least a couple will be down at any given time and during the course of a three+ hour event some will have problems (that are often fixed during the event).
It's really up to the TD and the player base on how picky they want to be. If you want to use the same five pins for league every week an operator might be happy to make sure they get regular service. If you want to use all ninety for a Stern Pro-Circuit level event weekly I don't think you'll find many operators willing to put in that level of effort.
