Chinajohn: 2. Offsetting for wind: each aim box (i.e. the blue box with the distance on) is 10mph from edge to edge or 5mph from the yellow triangle to each edge, of OFFSET wind from the perspective of the golf
Not sure what the '10mph' & 5mph means in context, John.
from I can figure the dark ydg/elev box is 5 yds on a side & is 1/2 the size of the pitching grid displayed for aiming approach shots. The grid is made up of 2ft squares.
bob, the important point on this system is you must be looking from the golfer's point of view, i.e. from the position of the ball, not from another camera angle, at that distance a full aim box equals 10mph of lateral crosswind (so you have to calculate how much of the actual wind is lateral, there is a guide for that too), and then you have to look from the position the ball lies in, at that scale it works very well.
Of course from that distance often you cannot see anything very clearly, but if you use the flash zoom, you zoom in on a portion of the screen but everything stays to the original scale, (i.e. from the position the balls lies in) only now you can see more detail and so adjust your offset which still has the 5mph half box (so you can use the yellow / green triangle below the aim box) or 10mph for a full box, (links in heavy winds).
Edit: So to clarify, using your picture above you need to go back to where the ball lies and then look at the aim box (in this case with the 11ft elevation and 112yd numbers in it) from that position the full box will equal 10mph lateral wind and from the edge of the box to the green (in this example) inverted triangle will equal 5mph.
