Average wind calculation

[DougBG]

Ballistics calculators have inputs for one wind speed and direction. Is there a method to average wind speeds and directions, as observed at different positions downrange, perhaps giving more weight to early deflections.

Position values

Assuming no terrestrial influences, the following values are close. Starting at the bench using equal segment spacing. These numbers are based experiments with a "Smart Flag" using a 6 PPC 65 gr @ 3300+ BC.258 I wish I could plug this data into a computer and come up with a formula that calculates the true relationship between flag positions!
3 -10, 6.5, 4.23
5 -10, 7, 4.9, 3.43, 2.4
7 -10, 7.5, 5.63, 4.22, 3.16, 2.37, 1.78
9*-10, 8.5, 7.23, 6.14, 5.22, 4.44, 3.77, 3.21, 2.72
*probe heads instead of string

Jerry, if you have a spreadsheet like excel, Take the strings of values and post them into strings of cells. Then highlight the values. Next select TOOLS, then create graph or some similiar command. Then choose the graph type you like, ie. line graph. It should give you a series of lines, one for each series of numbers.

Is this what you are looking for?

Thanks Joe

No thats not it. I emailed you.
