The trend of fresh harvest on the Vault with a mere 16% APR will likely depend on the amount of veYFI used to incentivize the vault. If veYFI is used to increase the incentive of the Vault, it will likely attract more users and result in a higher APR. This increased demand for the Vault will likely cause the APR to trend lower as more users take advantage of the higher returns. However, if veYFI is not used to incentivize the Vault, the APR may remain relatively stable or even decrease as more users become aware of the Vault and its potential for higher returns. Ultimately, the trend of the APR will depend on the amount of veYFI used to incentivize the Vault and the amount of users taking advantage of the higher returns.
