Ideal number of rental responses?

Hi Gang!

I'm just curious - what does everyone consider a "sweet spot" in number  of rental inquiries you receive on a unit you've listed, as an indicator of when you have hit the ceiling of how much $ you can get. 100 responses on zillow in 3 hours, you are probably pricing too low, 5 responses after a week, you are clearly too high. 

Wondering if people have found a good rule of thumb for what they'd consider an acceptable # of applicants, so there are enough to have consideration of, while pushing the limits on what the market will accept.
