I have played with a few ballistics programs, mostly JBM and ballistic FTE (iPhone) and the thing that continually amazes me is that I cannot help to make them more accurate by entering my own data. The predictions only tend to match up for sections of the trajectory, leaving you to tweak BC MV altitude or whatever else you can think of to get it closer to your actual flight, which usually creates more new problems. Is there a program that takes your real world tested data and uses it to extrapolate the rest of your trajectory? For example you give it zero range 100. Then shoot and record for 300, 500, 700, 1000, enter the atmospheric conditions and let it figure out the actual BC, mV, and fill in the gaps in your trajectory table. I have been a little out of touch with the gadget scene so I could be mistaken and su h a program exists, but can anyone point it out to me? Thanks.
