Generally speaking when shooting at distance you've got a bit of time but I never trust apps. I use 25yd increments from 100 (my zero) out to 600yds. Have a bigger Dope sheet that goes to 1000 in the bino bag. Moa/mil up rounded up or down as required. Wind full value at 10mph in moa/mil, easy to halve or add as required, rounded to nearest value. My Binos give me TBR so no need for an angle conversion table. All created on Microsoft excel, laminated, then taped to my rifle.
