You're being paid 17.1% to absorb price risk. Only ~17.1% of it is real fees — and they stop covering impermanent loss if ETH-UNI diverges more than ±254%.
Real fee/staking yield: 17.1% · token emissions: 0% of the headline.
Break-even fact: a ±254% move in ETH-UNI erases a full year of the fees you actually keep (~17.1%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
