    Zoom ???? What are you talking about ??? If i make the picture bigger i see only pixels, not a zoom.

    It's just for magnifying the ball to set the spin. You can use right-click zoom to center on where the cursor is. The Nikes don't have a convenient reference point like the Callaways do.

    JHarkness:

    I too like to use full backspin. Here is a rough formula that I like to use which works pretty well.

    add 5-7 automatically for full backspin.

    add or subtract 50% for headwind or tailwind (ex. 15mph headwind = additional 7 to distance)

    add or subtract 1/3 for elevation. (ex. 20ft downhill = 5 subtracted from distance.)

    183 + 5(full backspin) - 1(half of 3 for tailwind) - (1/3 of down elevation). For crosswinds, you need to atleast double whatever the wind speed is. (ex. 15mph crosswind = atleast 30ft aim adjustment.)

    Tweek the numbers until you get the right combination.

    are you talking about percentage or yards?
