Suggest Treatment For Cervical Ectropion

I had a cervical cryosurgery performed for cervical ectropion. The Dr. did the first freeze for 3 minutes, then the thaw, then the second freeze for 2 minutes. Every place that I've been reading has said that the cycle is a 3-minute freeze, a thaw, and then another 3-minute freeze. So, since the Dr. only did a 2-minute freeze on the second go 'round, does that mean the procedure won't be effective?
