The Nutshack Equation.

The Nutshack Rap Locus Equation

n = 19.048, Where n is the Nutshack Number; the approximate starting point of the Nutshack Rap where all instances of the word "Nutshack" have been removed from the song.
i = 13, Where i is the number of times the word "Nutshack" is said before the rap starts.
x = variable, Where x is the duration of any sub-video which replaces the word "Nutshack" in the video.
l = (x * i) + n, Where l is the Locus of the Rap's starting point in the song where "Nutshack" has been replaced with any video with the length of x.

l = xi+n
n = l-xi
x = (l-n)/i
i = (l-n)/x

Locus = (Replacement Length x 13) + Nutshack Number
Nutshack Number = Locus - (Variable x 13)
Variable = (Locus - Nutshack Number) / 13
13 = (Locus - Nutshack Number) / Variable

DEMONSTRATION:
	Say we have a Nutshack Video with a duration of 30 seconds...
	x = 30
	n = 19.048
	i = 13
	l = (30 * 13) + 19.048
	l = [360]     + 19.048
	l = 379.048

	Here, we see that the Nutshack Rap begins at 379.048 seconds. You will be examined on remembering the values of n and i.
	The AQA / EDEXCEL A-Level papers on memeology will not give you these exact measurements anywhere on the booklet, nor will they give you the equation for l.
	If l is calculated in an exam with 100% accuracy, or even slight deviation, you will receive full marks if you put down your working out.
	Failure to leave working out written for the examiner will result in a loss of up to 4 marks on a 7 mark question. If your worked out equation is wrong, you will lose all of your marks for that question.
	If the Variable fluctuates; i.e: A different video is played per "Nutshack", then the variable i will not be static; you will be expected to rework your equations to make up for this imbalance multiple times in an exam.
