Yeah, I think they can and you're right that would be a way of doing it.
But... I'd say it's possibly better not to do that, the reason is that if the chrono is set up to give the correct answer at the muzzle, we can easily check the chrono for accuracy against another chrono - like a combro for example. If the Polish one was set up to give a corrected figure for 10yds then it would be hard to check the calibration of the chrono. Not impossible, but harder.
