Rewards earned in new WBTC vault is not 30%


I’m a newbie here. I deposited WBTC (byvWBTC of Yearn) yesterday. The advertised yearly ROI for current TVL is 30% (for over $400 millions). Today the Badger Available to Claim showed pretty small number (about 6%). Is the rest of the reward paid in other type of tokens? Or do I have to wait 2 weeks for the vault to reach full efficiency to get the 30%? Please advise.
