This would also not work well in case of a dynamic algorithm that greedily tries to pay the whole amount at once, then splits it if it does not fit, with each split also being liable to splitting.
Such a dynamic algorithm would not know in the first place how many splits it will take, but it *will* know the total amount it intends to deliver.
