"I've even seen a 4:1 ratio of bid to ask"

That has happened, but not often. I have been using this disparity as a buying indicator. Simply, since the first of the year whenever the bids exceed the asks by more than a 2 to 1 ratio, I buy another 1000 shares. I believe that has happened every market day. I put the order in at the ask price but it is usually filled at a price that is .02 to .025 below that.

Only time will tell if this is a wise strategy.
