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 HoleFor 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.)
TerrainMultiply 100/(Terrain percentage) to the distance from hole. i.e. if the ball is on rough, multiply 100/95 to distance from hole
Hole HeightIf 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
WindTHe 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 =)
