Good luck on this. On the RM issue everyone is right in what they are saying of course but on a single factor the most important thing is not to reach your maxes too quickly so like 0311 said 4-6 weeks....so if you undershoot your maxes it won't matter very much especially since your "max" will be changing all the time anyway. So your in good shape.
BTW, your pant size, if you are a man, is your waist size. The part that hangs over your pants is your belly size. So use the lower number
