So, one value was duplicated, four near the end were shifted to the right, and the last field (Blue Alliance Goal Penalty) was lost. The good news is that you can calculate the BGP from the other values by using the equation:

BF = BG + BB - BP - BGP

If you shift the values and use the above equation to solve for BGP, consistent score details can be recovered for all but 43 of the 1,210 matches tweeted during week one. There were a number of matches that didn't get tweeted and some matches which got changed after the tweet went out (so you have to check against the official first match results pages).

In case you're wondering about the details, here's my understanding of the various fields:

RF = "final" score for red (unless it gets changed later by appeals to the head referee, etc)
RG = red goals
RB = red bonus for elevated/suspended robots
RGP = DOGMA (pdf) penalty accessed by the field
RP = penalties accessed by the referees

Likewise for blue.

thanks for this tom... it fixed the issue I was having... A couple questions though... Have you thought about a way to calculate the BGP value if the alliance had more penalties than goals(it would normally result in a negative BGP value according to your equation)... also, has FIRST mentioned if they will be fixing this issue for this weekend's regionals?

thanks a ton!

I'd just like to add that I'm using your app on my iPhone also
