I am going to be rolling out a tool that I use in my battle reports as well as what I use in campaign days to match up players based on army strength. It is a tool derived from azyr comp back in 2015 & 2016 and was updated for
GHB 2016 & 2017.
The tool allows you to plug in two armies and calculates their base probabilities and power indices based on their actual statlines and solid information, leaving an actual utilization field for things like abstract abilities to calculate an overall set of numbers you can look at in the end to see where your army weaknesses lie mathematically.
Right now I have it calculating the Average scores (a unit's performance against everything in the game), an Expected score (a unit's performance against only everything in the opposing army) and an Actual Score (what you plug in from your game). Additionally it shows you your efficiency, meaning for your damage output and defense what you get per point spent on that unit (showing you what is over and undercosted and where you could improve).
Older versions also calculated the bell curve of the entire game to rank your unit's base probabilities vs everything in the game, but the 2018 dataset is currently empty except for my Nurgle list and a Daughters of Khaine database since it takes an awful lot of work to populate everything and if I'm only using 20% of it I don't feel like plugging in all of the data, and users can just input that on their own.
This was based on a formula we had written for Azyr Comp, and before that was used to calculate power coefficients for
WHFB 6th - 8th edition for tournament play to make sure we were running top lists (it backed up our math). The end result of those many years of using it (though that was on a spreadsheet) was a tournament team of six players that routinely placed high and used this tool quite a bit back in the day to good effect.
So what the point of this thread is is to ask for some desired feature sets that I can plan on adding to make it more useful. This will continue being used this fall for our Firestorm campaign to help match opponents up with closer strength lists to allow casual players the ability to play without getting steamrolled (unless they request it) by much more powerful lists.
An example of the web-based data can be found at
http://www.louisvillewargaming.com/AOSStats.aspx though those numbers are now out of date.
They represent only the non abstract stats, so abstract abilities and the like were not incorporated on that website.
If you don't feel math like this matters, thats fine. I'm not interested in a debate/argument over that; that topic has been done several times over and this is for people interested in using statistics and probabilities to help gauge their lists better.
