The official statement of the rule is as follows (we reserve the right
to update this with clarifications as necessary):
Any data is allowed, so long as *no human judgement went into
producing it* (I know this is unclear, because human judgement goes
into any model, but we're going to try to enforce the spirit of the
rule as best as possible). So for example, all of the score and box
score data we provide, RPI, Sagarin, or Pomeroy-based scores are
allowed. Seeding, the results of AP polls, or other human-produced
rankings are not allowed. When in doubt, the rule is that the burden
of proof lies with you to show that no human entered into the loop,
but we can discuss specific cases.
