You will see running collections are different due to rounding issues. If your transactions are an odd number or your investor percentages don't divide up the transaction amount evenly, there will be a different running collection amount. On the last payment transaction, the system will attempt to true-up the amount to equal the target collection amount. In this case, the last transaction, the investor collection may not follow the usual math (Investor Amount - Fee = Investor Collection).
If desired, you may ask us to disable the "true up" method but you will have some syndicates with a higher or lower total running collection due to rounding.
