Here's my calculation file for Peachtree using the dataset from the FIRST website (thus there are no ERC or EMC calculations). Can you take a look at it and see why my values are different than yours? Most of the calculations are done using formulas and VBA, let me know if anything is unclear.
Also, how do you import data from Twitter to do your calculations? For my data, I had to copy/paste the table of values for rankings, match results, and playoff results into a text file, which I then imported into excel as a tab delimited file. Probably not the easiest approach, and I'd like to make it more versatile to handle other regionals.
