Ideal, if you're over your goal weight by 2# at the first weigh in of the month you would pay for that meeting and would continue to pay each week that you weigh in over your goal weight (2#). If the first WI of the month is good and say the following week you're over, you are still free since you have already weighed in for the month.

Once Lifetime, always Lifetime. You don't lost the status
