I'll "weigh in" on the discussion about losses that do or don't differ in subsequent IP journeys:
First time I did IP=11 lbs lost the first month
Second time I did IP=10 lbs lost the first month
This time=11 lbs lost the first month
My starting weight was a little higher the first time than either the second or third time, but not by much.
Reached goal 9/11/11. Restarted 2/17/15.
