I will say that the Shooting Chrony I use is a hunk of crap, but when it reads, the readings seem to be either damn close or close enough. When putting average reading into ballistic calculator and running bullets with pretty much known BC, the data and the drops match up close enough. So for me it works.

Edited to add the distances run are 100, 300, 400, 600.
