D-Plane Calculator

[rogue]

Hey Mike:

I have a couple of questions about the d-plane calculator.

Before I ask them, I was wondering if you could first please
define the following terms.
"HSP/AIM for CP=0"

Also, is the "AIM/SWING ADJUSTMENT" calculated in yards or degrees?

Thanks
Ed

Ed,

HSP/AIM for CP = AIM ....is in degrees and negative is left, positive right



AIM/SWING adjustment is in yards

hope this helps

Here is some more help with the D plane Calc

Thanks Mike and Matt:

In the D-Plane calculator:
If I follow the formula correctly,

(1) VPE = TAN((90-VSP)*3.14/180)

TAN is Tangent
90 is 90 degrees
3.14 is Pi, and
180 is 180 degrees

(2) HSP = AoA * VPE

(3) Aim/Swing Adjustment is calculated as follows:

((Length of Shot / 100)) * 1.75) * (HSP)

My questions are:
First, what does the 1.75 represent,
Second, how does this formula convert into yards?

(Length of Shot / 100)
the 100 is to move the decimal place two to the right,
for example:

150 yard shot is 1.50
233 yard shot is 2.33

I can understand how the HSP comes into the equation
but I am unsure about the 1.75

Thanks
Ed



P.S. A recommendation:
the way the calculator is set it does not round the Aim/Swing adjustment.
It may be useful to have it round as fractions (halfs) to the nearest half,
that is 5 ½ would be 5 and a half yards, etc
as opposed to 5.46520323

Hey Mike:

At the anti summit today, I was able to ask Fredrik Tuxen about the formula.

Aim/Swing Adjustment calculated by
((length of shot / 100) * 1.75) * (HSP)

He told me that the part I had a question about is used to convert degrees to radians, that is:

pi / 180 = 0.0175
which is equal to 1.75 / 100

Indeed, the formula simplified:
(Length of Shot) * (0.0175) * (HSP)

Tuxen added that the formula could apply to either yards or meters.

Thanks,
Ed

Ed,

There is no one better at Math than Frederik

Hope you enjoyed the Summit and got some useful tidbits for your game
