he probably means the area south of the olentangy exit, because thats the only 55 zone, or else he ment to type 65.
my dad was a state trooper for many years and what he told me is this:
they wont say "go out and write 15 tickets today". but they do know, through math and statistics and stuff, that there are X number of people breaking traffic law out there on the highways. if you have Y number of police to enforce it, that each one should catch about N% of X a day.
so they dont have a set number really, but if everyone at the post writes 10+ tickets a day, and you are only writing 3, your supervisor knows you are slacking off.
now thats not to say that they wont tell him to step up enforcement in a certain area or something. about 5 years ago, some new road opened up (i forget where, ill have to ask him) and it was implied that they should ticket cars going 1mph over the speed limit.
not sure if he wrote any tickets for 1 over, but i really doubt that he did. he isnt a dick like that haha. hed probably let you slide to about 10 over, because like i said earlier... he knows that if someone goes by at 75 in a 65, he could go write that guy a ticket, or he could just wait a bit longer and someone will come by at 90+
