The expectedYieldTokenValues are the debt notional (at target health factor) in the unit of account i.e MOET/USD: expectedYieldTokenValue = expectedDebt = fundingAmount * flowPrice * collateralFactor / targetHealthFactor. It doesn't not account for the fees associated with swapping (nor price impact) MOET to yieldToken on the DEX when we create the yieldVault (ie. yieldToMoetSwapper in the createStrategy), as a consequence: expectedYieldTokenValue < expectedDebt.The bridge fees are in FLOW and covered by the protocol.
