Marcelo,

Thanks for the response. I think I may not have explained clearly enough. The dates themselves do not really matter, it is the values corresponding to those dates that I need to average to "predict" what the next value needs to be to maintain a certain service level.

So if for days 1-5 of 22 my values average 150 and my service level agreement says I need to be at 80. Assuming that the rest of the days (excluding tomorrow) I maintain my level of 80, what does tomorrow's value need to be so the average of all 22 meets the service level of 80.

Hope that makes more sense.

Thanks,

Steve
