I wouldn't even worry about it.
Just shoot and confirm drops as far out as you can and record them with pencil and paper. Go into your ballistic program and play with the velocity number till the program outputs the same drop values you recorded in actuality.
I think when you have done that, the velocity figure you have determined works with all the important parameters in sophisticated ballistic software is more accurate than most readings you'll get over a chrono
YUP!
Same here. I just use software to give me approximate come-ups. Then after dialing at all the distances out to 1,000...I record the actual numbers and print them on my cheat sheets. Just too many variables to be an exact science...for me, anyway.
