USDMPegRecovery.sol#L100
The README says Once 40m USDM is deposited, 3Crv side of the contract starts accepting deposits. However, the code accepts 3CRV deposits after 4M USDM is deposited instead.
Specify the threshold as an internal constant, and use underscores for readability. I also recommend double-checking the values of declared variables in all contracts, such as step and concurPerBlock.
