As long as you clear out all the hair in the treated area in less than 6 weeks, each time you should be on schedule to get finished less than 24 months. If you fully cleared everything in 3 weeks or less each time, you could finish sooner.
Again, the answer is still yes, you would get finished on that schedule if you manage to clear out all the visible hairs in that rotation of 6 to 8 weeks.
Of course, you may be looking for someone other than me to answer that question, in which case... I wish you luck with that.
