Double counting: one crew, and the same hours in the total twice

Type each claim line with its resource, weeks, event and route. Pairs that value the same hours twice are named with the amount counted more than once, and no claim is called overstated.

Live result

On the confirmed basis, 80,000 cost units appear on more than one valuation route.

One declared share and the duplicate amount it produces

Comparison basis

Equal resource and event labels are your declaration that the lines describe the same thing at the same information state.

20percent

This is the one assumption moved by the chart and sweep. Zero declares that this line carries none of the compared resource amount.

How the answer sits across the values sampledA rail of the 5 values sampled, from 0 percent to 40 percent in steps of 10 percent. Across the values sampled, the whole duplicate amount stays 80,000 from 20 percent to 40 percent, the highest value sampled. The nearest value where it changes is 10 percent, where it becomes 40,000.first change10 percent20 percenton the page

What an unchanged region does and does not prove is set out in a short lesson.

The sweep samples only the values you entered. Between samples the answer is not checked, so read the boundary as observed, not proven.

Here is the maths

The formula, in words

For each resource, event and whole week, group the covered amount by valuation route. Add the route amounts, subtract the largest route amount, and then add those weekly excess amounts. Candidate pairs are named separately and are never added to form the total.

A worked example

Typed line A carries 100,000 cost units a week and declares 20 percent for Site crew, so its covered amount is 20,000 a week.

Typed line B carries 20,000 a week for the same resource and event through another route during weeks 10 to 13.

The exact overlap covers 4 whole weeks and is 4 times the smaller route amount, so 4×20,0004 \times 20{,}000 equals 80,000 cost units.

Typed line C names another resource, so it contributes no intersection to that pair.

Why pair values are not added

If three routes carry 20,000, 20,000 and 10,000 in one exact week, the excess is 20,000 plus 20,000 plus 10,000 minus the largest 20,000, which equals 30,000. Adding all pairwise minima would return 40,000 and count part of the same overlap twice.

What this does not model

It does not establish that equal labels identify equal scope, classify a head of claim, test causation or criticality, price a line, choose a route to reduce, or decide entitlement, compensability, accuracy or overstatement.

What the sweep moves

Only the first line's declared included percentage changes. Every label, week, weekly amount and other share holds fixed. In the worked record the total grows to 80,000 at 20 percent and stays there because the second route carries only 20,000 a week.

The calculation domain

The contract accepts 2 to 40 lines, labels of 1 to 60 characters, inclusive weeks from 1 to 520, whole weekly amounts from 0 to 1,000,000,000 divisible by 100, and whole shares from 0 to 100 percent.

Permanent refusal

Requests to choose a deduction route, decide entitlement, classify compensability or label overstatement are outside this calculation and return no answer.
