Very nice... they need to lose the grey background that prints with every sheet - including the small range card. ~2" x 3" of useful information, the rest of the page is wasted ink.

First of all, what a great program! My question relates to the wind compensation. My simple ballistic chart or field chart I put in zero wind and zero wind direction. My print out shows a wind adjustment...why? or better yet, how can I have an adjustment for wind if there is no wind? Example, at my zero range of 200 yards the chart shows 0.0 drop at a 0 incline but a 1.0 for wind. ?? Additionally how do I read the wind adjustments? Are they 1/4 moa "clicks"? so a number of 3.6 represents what? How is left or right distinguished? Or if the wind is blowing left to right I would adjust left 3.6 what? Or right to left it would be the same adjustment but to the right? Your assistance can help me with my confidence in using the software. Also, I agree with others that you need to remove the grey background as it is just a waste of ink. Thank you....:)

I don't know if i'm just an idiot or if there is an issue with the spread sheet on this calculator. If I scroll between 10, 50, or 100 yard increments, my come up in inches changes at a set range. For instance, at 400 yards, it calls for 27" of correction when using 100 yard increments, yet when I switch the calculation to 10 yard increments, my correction says just 13". Did I enter something in wrong or does it do that to everyone?
