 The "schedule" of claims is based on a count and time frame. Recall the estimated claim count from the adaptive number of tiers? We use that same number to compute the schedule. The schedule starts immediately after the draw is awarded, and is set to take one quarter of the draw period. This provides plenty of leeway in the event that there are more prizes, statistically, for a given draw.  It's highly unlikely that a draw will see a variance of double the expected prizes, so we believe a quarter of the draw period is sufficient.

 The Prize Pool determines whether a user has won a prize by checking if a pseudo-random number is within a certain range.  The PRN is generated such that it is unique per draw, tier, vault and user. The number range is used to tune the odds based on the prize frequency and the user's eligibility.
