How many people are in a typical class?

I wish it were consistent enough to give a reliable number but it’s not. By tracking attendance and doing some quick math I can show that we currently average 13-14 people per class but that can be misleading. Some classes may have as few as 3 or 4 people while others may have more than 20. Generally speaking, weekday morning classes are smaller, weekend classes are larger, and weekday evenings can go either way. It’s a crap shoot.
