now to count boxs for yrds just start from center where its at an say wind is from right to left an u need to move it 10 yrds to right,,, line left side of blue box up where the right side of box is now,, heres a pic of ten yrds...

so now as u move away from pin u can go by halfs or full movements.....
now one last tip to figure out how far u want to move for cross winds you take the distance of shot an times it by wind but u have to use decimal if the distance is 100 an higher here i will show ya....
say you have shot that 99 yrd an you have 15mph cross wind,
take wind 15 x .99 = 14.85 witch i would round off to 15 yrds u need to move marker witch that would be one full box movement an then another half movement .
now anything 100 an up say its 167 yrds an 20mph wind..
take wind 20 x 1.67= 33.4 yrds so that would be 3 full box movements.
now this is not 200% on the money but its been dam good to me all it takes is lil time an practice an get the feel for it an make your own lil adjustments...
gl to ya an hav fun......
