HDM terminology used in this project compared to AHP
Levels, HDM, AHP
Level 1, Mission, Focus
Level 2, Perspective, Actors
Level 3, Criterion, Objectives
Level 4, Alternative, Scenario

What's new in this iteration?
Step 1:
Density - a customizable baseline measurement to make account of outliers
Focus charts - deep dive reference when debating one individual implementation over another
Skip level comparisons (Alternatives "Level 4" to Perspectives "Level 2")
A standard deviation matrix based inconsistency score. I suggest that you accept either CSAHP consistency score calculated in the spreadsheet. If either one falls below .10 then you should accept the users ranking as valid.
Step 2:
Desirability Global Weights based on Perspectives weighting (rather than local weight mulitplication) from step 1
New Sensitivity calculation

Note: The number of variables 4,5,6,7, and 11 have been put into the spreadsheet and tested. If you want to use variables matrices of 3, 8, 9, or 10 you will need to create that in the tool spreadsheet (work backwards from 11 and make space in the spreadsheet).

Note: The reciprical scores on the grid tab are plus oned so that the total range is effectively larger* (yet the decision maker only gets a 1 to 10 scale to respond to). This tweak creates space in range which solves the AHP problem of mis-ranking/re-ranking the average vis-a-vis a raw sum (which would give a decision maker the wrong decision to choose). That is the grid is "expanded" to provide separation of scores thereby never changing rank order. Thus this CSAHP model raw sum will always equal the the ranking order.
Example:
If a cell score that is being inputed (there in only one value per pair because the reciprocal is derived), then the derived reciprocal is calculated based on the follwowing grid:
Constant Sum Value: Grid Input Score, Reciprocal Derived
1: 0, 9
2: .11, 9
3: .25, 4
4: .42, 2.33
5: .66, 1.5
6: 1, 1
7: 1.5, .66
8: 2.33, .42
9: 9, .11
10: 9, 0
The reasons for these scores is because of the (10-n)/n calculation for the reciprocal.
Reviewing this grid setup shows that there are 20 possible grid data points from the 10 point scale:
Constant sum scale in Excel
1, 0 = 2 data points
2, 0.11111 = 2 data points
3, 0.25 = 1 data point
4, 0.42857 = 2 data points
5, 0.66667 = 2 data points
6, 1 = 2 data points
7, 1.5 = 2 data points
8, 2.33333 = 2 data points
9, 4 = 1 data point
10, 9 = 4 data points
Larger because effectively a 1 data point can be considered a minus 1 while the 4 data point can be considered a plus 2. If the 2 data points are all equal to one then the effective range is now 12 instead of 1 to 10.

Note: A constant sum scale of 1 to 100 also provides enough room in the matrix to overcome the misranking problem but some survey tools (like Google Forms currently) will not allow for a 1 to 100 scale. The survey taker shall ignore the 1 to 10 numbers (if shown as in Google Forms) and instead treat the linear scale checkboxes as a comparison relative to how much they would pick one variable over another.

Note: The Alternatives (Level 4) are an optional component (and an additional spreadsheet for processing output of survey) of the model in order to include cost/aquisition decisions and management personnel into a final report.

The factorials are roughly the number of rows needed to do an HDM calculation.
4! - 4 × 3 × 2 × 1 - 24
5! - 5 × 4 × 3 × 2 × 1 - 120
6! - 6 × 5 × 4 × 3 × 2 × 1 - 720
7! - 7 × 6 × 5 × 4 × 3 × 2 × 1 - 5,040
8! - 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 - 40,320
9! - 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 - 362,880
10! - 10 × 9 ×8 × 7 × 6 × 5 ×4 × 3 × 2 × 1 - 3,628,800
Thus the limit for using Excel for HDM calculations is 9 factorials.
Excel's maximum row limit as of year 2023 is 1,048,576, and columns are limited to 16,384.
