Additional bonus system detail: Points must be used within 48 hours of earning them. There are currently 4 ways to earn 2 points every 24 hours. This means that a player can have a max of 16 points available at a time. One could save up points and then have up to 160% production for 10 turns or have +40% attack power for 120 turns/40 attacks. It seems that the production bonuses would be best used at the end of playing your turns.
