Yes, it is very strong. A normal range for me has been 55-64%. Contact rate though isn't THE most important one - it's like "time of possession" in football - if you don't score points, it's meaningless.
The only stat that matters is ROI. How much do I get back vs. how much I've spent.
Everything else is academic, unless the comp system was changed when I wasn't looking!
But it is tough to score w/o possession... just like it is tough to sell if you cannot get the prospect on the phone. Also, assuming all things being equal... the more you reach the more you will sell...
This is simple physics, right...
