Reimbursement is only a consideration if the loan closed with a significantly understated APR or FC. Until the moment the borrower becomes obligated (by signing the note) you can continue delivering updated TIL disclosures and the only one that matters (for reimbursement purposes) is the one immediately preceding consummation. I have no idea how the waiting period rules work, so someone else will have to help with that.
