Formula

MER fraction = (14×Source + 26×Target + 14×Head + 8×Proposer + 2×Sync) / 64, with each term multiplied by its timely participation rate.
ETH/year = Baseline_ETH × MER_fraction. APR = Baseline_APR × MER_fraction.

Notes

Consensus-layer only (excludes EL/fees/MEV). Baseline 0.997 ETH ≈ 3.11% APR.
Head has no penalty if wrong/missed after Altair; you simply don't earn it. Target/Source can incur penalties during inactivity leak periods (not modeled here).

Inputs (timely participation, %)

Target flag (timely within 32 slots)

26/64 weight

Head flag (timely = inclusion delay 1 slot)

14/64 weight

Source flag (timely within 5 slots)

14/64 weight

Missed proposals (as % of your proposals)

Proposer 8/64

Missed sync duties (as % when selected)

Sync 2/64
