Well, ours has 1 per day (right before lunch) and it's outside unless it's too cold or rainy. Then there is Health and Wellness, which takes place I believe 3 or 4 days out of the week, which is essentially another 'recess' break. Then on Mondays they have PE.
For our school, (ours go to a Charter School) I would actually agree that there is 'too much to teach' to be having several recess breaks per day. (mind you, this does NOT mean that the kids just sit at their desks ALLLLLLL DAAAAAAY LOOOONG, just because there is only one 'recess' per day. )
Oh....and when we used to homeschool, we had 'recess' written in our schedule daily, however we only ever got around to doing it MAYBE once per week. So they are getting more outside time at school than they were when we homeschooled, but that's just us.
