Does the software tell me somewhere what my standard deviation is?

The old version used to calculate it. Its on my TODO list to bring it into version 2.0 ... I havent had any requests for it till now, but I can bump it up a bit and get it in... its not a big deal to add.

I usually calculate all that with my Excel reloading log (including MAD, ES, & 95% SD). Since the straight SD is technically only 65.4% of the expected variance range, I like to calculate the SD to the 95% level (2x SD) which I then add/subtract from the median velocity to arrive at an expected +- range that my reloads should fall within most of the time. Its a nice feature for some situations but in general the +/- velocity spreads can be eye opening (disappointing, alarming, scary etc) on otherwise good loads.
