6i Beam Impact
6i Beam Impact Tutorial
Requirements:
Good mental sum or a scientific calculator
Good accuracy in power
In this tutorial, I take wind 0° as the vertical, 90° as horizontal.
To begin with, 6i beam impact can be calculated based on a simple formula.
The formulas provided will be accurate from a dist of 8 - 38 yards.
There are basically 4 factors to consider in 6i Beam Impact:
-Distance from hole & Terrain
-Hole Height
-Wind
Distance from Hole
For every distance, there is a slight change in the formula, I will break it down into 2 parts:
From 8 - 25y: Multiply 1.2 to the distance from hole.
From 25 - 38y: Multiply 1.25
For 40y and above: Multiply 1.4 (This is just a rough estimate and to beam at 40y and above is not that easy.)
Terrain
Multiply 100/(Terrain percentage) to the distance from hole. i.e. if the ball is on rough, multiply 100/95 to distance from hole
Hole Height
If the hole height is
-between +0.3m and -0.3m, the changes can be consider negligible.
-from +0.3m - +0.5m, add the hole height to the power needed
-from +0.6m - +1.0m, add the hole height and an additional 0.5 to the power needed
-from +1.2m - +1.5m, add the hole height and an additional 0.7 to the power needed
Wind
THe further the distance from hole, the more wind effect there is. In this case, I take it that the wind is directly against you.
From 8-10y, add Wind Strength(WS) / 6 to the power needed
From 10 - 14y, add WS / 4.5 to the power needed
From 14 - 25y, add WS / 3.5 to the power needed
From 25 - 38y, add WS / 3 to the power needed
Combining all, the average equation looks like this:
1.2 * Distance from hole * 100/100 + hole height + WS / 3.5
I know this looks confusing so I've included examples.
Example 1:
Distance from hole: 15y
Terrain: 100%
Wind: 1m 0° against you
Hole Height: 0m
Calculation:
1.2 * 15 + 1 / 3.5 + 0 = 18 + 0.286 = 18.286y
Hence, percentage power needed = 18.286y / 140 * 100 = 13.06%
Please note that if you shoot 13.1% or 13%, you will miss your beam impact. As I mentioned, you need accuracy in power.
Example 2:
Distance of hole: 28y
Terrain: 95%
Wind: 7m 40° against you
Hole Height: 1.12m
Calculation:
1.25 * 28 * 100/95 + 7cos40° / 3 + 1.12 + 0.5 = 36.8 + 5.36 / 3 + 1.62 = 36.8 + 1.79 + 1.62 = 40.21
Percentage Power = 40.21 / 140 * 100 = 28.72%
The angle at which you should aim will be up to your own estimation. There is no formula for that.
That's it for the beam impact tutorial. Happy beaming =)

hi elfen, just some addition to your beam impact tutorial. have been using some formula, with rather good success.
this BI formula concentrates mainly on power and uses 6Iron, and here is an example:
Hole distance: 30
Height: 2
Wind: 4m headwind
Terrain: 100%
Formula is: 30 + 2 + 1 - 4 = 29
Power to use is: 29 / 10 = 2.9 bar
For terrain 95%, add 2 to power calculation, and for 90% add 4.
For wind, 1m: 0.25, add and subtract accordingly. that is only for perfect head and tailwind; angled winds one has to estimate how much to add/subtract.
Hope u can try this BI formula out, and if it works, might wanna add this in your blog. hope it helps!
