Does Exbal have an entry for chrono reading and determine MV when chrono is 10' away from the muzzle?
If so I can't seem to find it.

Roy,
I can't imagine that 10 feet is going to make much difference in your velocity reading. I wouldn't worry about it. I'm sure you validate your drops.
I'm with TrueBlue on this one....I may be missing something, but I don't see a benefit worth the time to code in the enhancement.
The Trajectory Validation feature will calculate what your true velocity is if you are checking your drops for different distances.
I think a more beneficial enhancement would be for Exbal to calculate a true BC when using the Trajectory Validation, as it only calculates velocity.
I've found the velocity difference to be 10-20 PFS based on where you set up your chrony. Exbal doesn't correct your MV it changes it to what it needs to be to make future calculations. It "fudges". The further away you get the worst it can be. With exbal you probably won't ever be using the correct MV or BC. You'll be using #'s pulled out of the sky that seem to work up to a certain distance then Drag model is the next hurtle. You won't get over that one with exbal.
I agree that for many there may be no benefit as far as hunting goes. hunting targets have big kill zones(large game). If your like me, Roy, and some others here, you'll get frustrated with "close enough". You'll want your impacts on target to only vary in their elevation because of your (my) less than perfect skills not because of less the perfect software predictions.
Please don't be offended by my response as It wasn't meant to offend. Just wanting to point out that some people prefer a little more precision than others.
As an example, If I go to the range and shoot paper at 500 yards using my software for predicted drops and I print a group that is .5 MOA low or high it really irritates me. My group could be two MOA in circumference but I want the center to be split by the horizontal line on the target. Any one of the shots would have harvested the intended game at that distance but the prediction isn't precise.
