You're being paid 9.21% to absorb price risk. Only ~6.59% of it is real fees (the other ~28% is decaying emissions) — and they stop covering impermanent loss if YMVOG-USDC diverges more than ±111%.
Real fee/staking yield: 6.59% · token emissions: 28% of the headline.
Break-even fact: a ±111% move in YMVOG-USDC erases a full year of the fees you actually keep (~6.59%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
