We also had some problems with the provided sample code (java) detecting distance, so we're in the process of writing our own distance computing method.

What I did last year was just look at the apparent size of a vertical side of the target, and then compare that to the actual size. It's simple to figure out range from that proportion.

I did have to correct the reported values, but I'd recommend just getting the first part of what I said outputting values, then do some empirical testing, plot the values in excel (computed distance v actual) and then generating a trend line. The equation of that line should correct your calculated distances pretty well.
