Yes, that does look promising, though I wish the range was at least a foot or two more.

I could always use a lookup table. Or, I've noticed in a lot of exponential curves the reciprocal of a reading often fits on a straight line, ready to be used in an algorithm. (I'm no mathematician, so please forgive me if this sounds absurd). Will have to confirm it is so for this sensor in Excel.
