Thank you for this! Very usefull to a lot of people!
I fixed APY and daily issuance. I previously thought daily issuance was a constant, but it’s actually adjusted according to minted and burned GRT.
Some calculators made by indexers don’t take into account “planned delegation” and/or have a constant daily issuance (i.e. 821,917.81 which is 3% of 10 billion divided by 365).
