New SPS tokens will initially be added to the various reward pools at a rate of 37,500,000 tokens per month and will decrease uniformly across all reward pools at a rate of 1% per month, meaning that after one year the monthly contribution rate to the reward pools will drop to 33,239,400 and after 5 years it will have dropped to 20,518,400 SPS per month. These rewards will end after 65 months and at that point no more SPS tokens will be created.
