Measure value based selling behaviors, # of contacts of revenue?

A recent client established an arbitrary contact level for his value based sales representatives; 15 contacts on existing customers per week to retain business, 25 contacts with prospects to attract new business. First, I feel 40 contacts on a weekly basis is too much; especially if they are to be face-to-face and have some content. But this is a measurement of activity that many sales organizations focus on and I agree that all sales is a numbers game - the more you contact the more business you will get. There is also a monthly revenue objective that includes annualized revenue to retain a client and the dollar value of new business. In my opinion this is quantity vs quality of sales visits. There must be a critical mass of client and prospect contact but 40 seems arbitrary and would produce more of a "howdy call". How would your sales force react if you told them, "I don't care how many calls you make, as long as you make the revenue target."
