Methodology

• Validator APR (%) is calculated for each epoch as:

100 * epoch rewards * estimated epochs in 1 year / post_balance_sol

where:

• epoch rewards: rewards received in epoch
• post_balance_sol: The amount of SOL in the account at end of epoch
• estimated epochs in 1 year = 365.25 * 24 * 60 / average length in minutes of previous 15 epochs
