This is all very easy and you can do it on a spreadsheet - without clocks lols,
Input values for wind, angle, distance and elevation:
Headwind/ Tailwind = 4.4% & 3% respectively (for a Bilko approximation) times the distance divided by 10, times the wind times the cosine of the wind angle (in degrees) plus elevation divided by 3
Sidewind = the wind times distance divided by 70 times the sin of the wind angle (in degrees)
In maths the 3 main forumae are:
Headwind component: input this in to excel
add this to the wind figure you input in B1
Tailwind: input this in to excel
add this to the wind figure you input in B1 (notice it starts with a minus)
Side wind component: input this in to excel
Wind angle is measured with an on-screen protractor overlayed on screen using the software 'custom desktop logo' and between 12 o clock and 3 (clockwise) for headwinds and 6 o clock and 3 (anti-clockwise) for tailwinds.
The lateral distance from the flagstick can be measured using a home made T-square and taking the flag to be 7foot tall, again you can scale and overlay such a gadget on-screen using the magnificent 'custom desktop logo'
Or just download somebody elses effort for the no-brainer version, lols.
It's just a 'showing off exercise on my behalf don't panic, lololos
