Clarify the description of the contract value distribution

[jpmckinney]

The double usage of percentages confuses people:

The sum of the top 1% of tender values doesn't exceed 50% of the sum of all tender values.

We can try using words like 'rank' or 'percentile' – or split the description into 2-3 sentences to describe the steps of: ordering values, summing all values, summing top 1% values, making comparison.

Any suggestions? Feel free to update it in the source code @jpmckinney. I think you have rights to created merge requests and even merge those :)

Instead of:

The sum of the top 1% of tender values doesn't exceed 50% of the sum of all tender values.

Make it:

The sum of tender values in the 99th percentile is greater than the sum of the remaining values.

@duncandewhurst @yolile What do you think of?

I think people are more likely to understand % than percentile as the former is commonly used but the latter requires some (basic) knowledge of statistics.

How about:

The sum of the top 1% of tender values doesn't exceed the sum of the remaining values.

Alternatively, I think this is easier to read but leaves the ranking by value somewhat implicit:

The total value of the top 1% of tenders doesn't exceed the total value of the remaining tenders.

Another option could be to provide a more 'plain english' description which sacrifices some accuracy before the more accurate description:

The value of the biggest tenders isn't out of proportion to the rest of the tenders: the sum of...

The 1st and 2nd options are fine with me. The UI is presently for trained analysts interested in precise methodology – not for less technical users who just want a general description of the check.

Same!

@hrubyjan Let's go with:

The total value of the top 1% of tenders is less than the total value of the remaining tenders.
