Score sensitivity: does the order of operators survive different weights?
Sensitivity analysis asks whether the order of betting sites survives different weights for the five criteria groups. We recompute scores under equal weights, double weight on safer gambling and double weight on payments. On 7 November 2026 no real scores exist, so the real results are not yet available.
How is the test done?
Each group score is turned into a share of its group maximum. A weighted score is the sum of weight × share, with weights normalised to add up to 100.
We then compare each operator's place under four weight sets: the main weights, equal weights, double weight on R and double weight on P.
The normalisation rule is stated here and will be repeated on the methodology page.
Bottom line: Group shares are reweighted and operators are re-ranked under each set.
Which weights are compared?
| Weight set | L | R | P | M | S |
|---|---|---|---|---|---|
| Main (WS-1 v1.0) | 20 | 25 | 20 | 20 | 15 |
| Equal weights | 20 | 20 | 20 | 20 | 20 |
| Double weight R | 16 | 40 | 16 | 16 | 12 |
| Double weight P | 16.67 | 20.83 | 33.33 | 16.67 | 12.5 |
Doubling R takes its weight from 25 to 50 before normalising; doubling P takes it from 20 to 40. The other weights are rescaled in proportion.
Bottom line: Four weight sets, each normalised to 100.
What does a worked example show?
Group shares below are made up for illustration. They are not data on any operator.
| Example operator | Main (WS-1 v1.0) | Equal weights | Double weight R | Double weight P |
|---|---|---|---|---|
| Operator X (example) | 69.50, place 3 | 70.00, place 3 | 67.60, place 3 | 66.25, place 4 |
| Operator Y (example) | 69.00, place 4 | 70.00, place 3 | 65.20, place 4 | 67.50, place 3 |
| Operator Z (example) | 72.50, place 1 | 72.00, place 1 | 76.00, place 1 | 68.75, place 2 |
| Operator V (example) | 72.00, place 2 | 72.00, place 1 | 69.60, place 2 | 75.00, place 1 |
Operator X has shares of 0.8, 0.6, 0.5, 0.9 and 0.7 in groups L, R, P, M and S. Under the main weights its score is 69.50.
Under equal weights Operators X and Y both score 70.00 and share place 3.
Bottom line: The same operators can change places when weights change.
What are the real results?
The key figure will be the number of operators whose place changes by no more than one across all four sets. It needs scores from the comparison matrix, which has none on 7 November 2026.
The table of real places and the matching CSV will appear here once the matrix is verified. Equal scores share a place, and ties are listed alphabetically.
For the operators in scope, see the inclusion log.
Bottom line: Real results wait for verified scores.
