[QUOTE="Brown Dog, post: 210730, member: 1622"] Hi Ward, Hope you are well! I think the 2nd part of your explanation needs a wee tweak :) The reason for your 1st point being spot-on correct is that applying the cos to comeups (or drop) reflects what is going on ballistically, applying it to the slant (laser) range does not. I'm going to quote myself from a while back: ...and as a common-sense check: So, to restate myself: The reason for your 1st point being spot-on correct is that applying the cos to comeups (or drop) reflects what is going on ballistically, applying it to the slant (laser) range does not. Meant helpfully! :) All the best :) Matt PS. Thought you might like this pic of a rather technically challenging set of circumstances that faced me earlier this year: [IMG]http://i19.photobucket.com/albums/b162/thebrowndog/Slide1.jpg[/IMG] It won't surprise you to learn that we noted a significant vertical wind effect!
