Methodology

1. Pulls match results from FTC Scout
2. Applies modified chess Elo formulas:

   # Point difference weighting
   math.pow(math.log10(1 + abs(teamScore/2 - opposingScore/2)), 2)

3. Normalizes for event strength using:

   0.51 * math.log((-(highscore - region_score)/highscore) + 1, 10) + 1
