Here's a similarity matrix of all brackets, where 0 is a comparison with yourself, and the maximum possible difference is the full bracket, which would be 448 points. I tried out google sheets' color scale on this sheet, if it's bothering you, the second sheet is just the first without the conditional formatting, or you can make a copy and manipulate it as you like.
The Cookie line/columns also double as a measure of points risked vs. the cookie.
good job!
