@Cipherhoodlum @wikussound @100trillionUSD The charts without the zig-zags aren't taking actual historical issuance rate into account, and are instead assuming a set rate of BTC issued every 10 minutes. The charts with the zig-zags account for times when actual issuance varied from 1 block reward every 10 min.
