What is exact?Farm payout is exact from the retained manager reward transfer. Device reward basis is exact from the live on-chain processor rewardContribution field, and is shown here in raw basis units rather than ACU.
What is derived?Derived device payout is calculated by allocating the exact farm payout across devices using each device's exact reward-basis share.
FormulaDevice basis share = device reward basis / total farm reward basis.
Derived device payout = exact farm payout × device basis share.
derived_payout = farm_payout * (device_basis / farm_basis_total)
For epoch 3,753 on this page: derived_payout = 0.011322 * (device_basis / 11,797,565,033)
When is it strongest?When payout epoch and reward-basis epoch match. That means the device share basis and the farm payout belong to the same epoch.
Who is eligible?A device must have a retained processor heartbeat in the previous epoch and a positive reward basis to appear in the payout table.
Why can this differ from canonical phone payout?The chain exposes exact processor reward basis and exact farm payout, but not a long historical canonical per-phone payout ledger. This page shows the best aligned allocation model from those exact inputs.
