When deciding whether I think the advisors are over-worked I calculate the numbers backwards. So it's different for every shop, but let's take an average store.
Techs are 125% efficient
The average R.O. contains 2.5 hours
So for a 8 hour day each tech needs 4 R.O.'s to maintain their performance (2.5 hours x 4 = 10 hours). I think that the average advisor should write 18-22 R.O.s a day, so for this example the ratio would be 5 techs to every advisor.
I think there is some give in that system, like if the advisors are averaging 3.3 hours per R.O. due to time spent upsell we could back down the daily number written from 4 to 3.
Given the way you separate R.O.s (WTY vs CP) then I think that maybe you're staffed at a normal level and you should look towards redelegating some of the activies that the advisors are doing. I don't know your situation, but let's say that the advisors are also acting as shop foremans and doing some quality type of control or fielding technical questions. I think you'd be better off assigning a tech as "Lead Tech" and pay them a few bucks to handle this load instead of bringing on a new advisor's salary.
