To normalize your calculations, you might try plotting # pins per unit 
area, graphed on a time scale of # hours billed.  (or perhaps multiplied 
(or divided?) by # hours billed).  This would show proportional density 
as a function of billed hours.  Greater slope then indicates higher 
productivity.

Be sure to put the presentation graph in a nice powerpoint slideshow 
with colorful borders and imaginary (whether attainable or not) goal 
lines.  Bean counters always get an imaginary sense of importance when 
shown fancy graphics.

Good luck

If you know of this, know of other reference material for this sort of thing, or just want to tell me what I ought to do. I'd appreciate it (I think...).
