We need a method by which to approximate the workload-per-day of Niki. These stringent calculations will unearth a value for the units of "Niki", which we will use to plot the data for the Primary 'Y' Axis of The Diserroneous Graph Of Wonder...


We must first establish a link between Death, & Niki:

We can state:
"100% of all deaths in Brighton are processed & stored by Niki."
Since the % of people dying in Brighton each day through drug abuse is considerably Greater Than (but not Equal To) the % of those dying from Trench Foot, we can safely conclude:

"Youth culture expends many more "Niki's" per day than the fallout from WW1"
We store this variable for later use.

We then need to ascertain the square root of "Niki", but we needn't calculate this, since we already know that Niki divided by Niki will always equal "Niki"

We can therefore state:
"Niki" to the power of "Niki" = 1

Now comes the tricky part: Dissecting Niki

Nicola - Claire Savage = 100%

I see you've already deClaired (see what I've done there?) the first part of this equation: "Nicola" minus "Claire".
Unfortunately, you've left out an "equals" sign. The complete equation would read:
Nicola - Claire = "n", (where "n" equals "Savage"), which is then rounded DOWN, to the nearest integer.

Having followed this tricky formula to it's logical conclusion, we now have a value to carry into our graph:
1% = 1 whole "Niki"

1. It takes 5 "Niki's" to process 1 whole "Death"
2. It is possible to expend no more than 100 "Niki's" in 1 "Day" (where 1 "Day" = 7.5 hours)

Note: Should Niki spend more than 7.5 hours at work in one "Day" the value of "Niki" will be Less Than or Equal To the additional time spent at work. No extra "Niki's" can be assigned in such a case, since 100% of Niki still equals "Niki", and the poor girl can only process so many Deaths Per Day (DPDs).
