I don't want to spend time on something if the data is not reliable. If anyone is interested in pursuing that, you are welcome to modify my macros. All the macros in my spreadsheet are not protected. It includes all code needed to assemble and solve the matrix for you.

Nathan was asking about ETC, ERC and EMC which have nothing to do with matrices or OPR. And they are all calculated automatically. I just haven't published the latest version of my site.

Actually matrices inherently has an equal potential of inaccuracy. Digging through my threads I talk about how my algorithm is actually executed and the resolution it gets over OPR. Matrix algebra looks at the big picture, but it doesn't look match to match. ETC does look match to match. Point inflation affects both in different ways. Also I can tell which alliances finished in which place with minibots. So if someone has an EMC of 30 I KNOW in every qualifying match their alliance put up a winning minibot.
Also I calculate your team's contribution to each match, for the robot. OPR does as good a job as it can using traditional mathematics. I use CS algorithms to calculate my #'s. That being said there are still issues with point inflation that are inherent in any system. Some teams will have the luck of the draw. I have an idea of how to fix this for the ERC but it will take a bit to implement.
If someone had a java function for calculating OPR I could quickly implement it. ETC and OPR look at a teams contribution from 2 separate directions. I believe by utilizing both that the values it will hone in on a team's true contribution.
