How does a minimum value of -15.58 dBZ and a maximum value of -5.38 dBZ result in an average of -1.19 dBZ?

This program is going to lead to the end of my sanity, whatever there is left, especially since I'm not the one writing it.

Extremely large values of 1.19?

I suspect it's something to do with the quantity of samples and/or the logarithmic units.

Is this any help?

It's possible he's not averaging the way I think he's averaging, but it should be a straight average. I have a feeling it's a bug between the filter I'm using on the data and his average pulling from the unfiltered set. I've already lined up a meeting with him tomorrow to straighten it out. Delays, delays... :-)

...or it could be a bug in the program. ;)
