Pool stats are now running on a 1 hour delay.  Current round stats/estimated reward have been removed to remove any way to scrape data from the website to determine when we have started a new round.

Anybody using the API should remove the following pieces from their code:
  estimate_reward, round_shares, round_stales, round_time

They will be taken out of the API in about a week.  Until then they have been filled in with dummy data to avoid breaking gadgets/parsers, as well as give me some good stats on how much speed is involved in pool hopping.
