Hap, I believe you are thinking of ACH Credits.
If I am reading this correctly, the originating bank is actually originating a debit, those funds availability you listed do not apply. As a general rule, most banks will place a 2 day hold on the funds to allow for the possibility an NSF return.
The online bank I bank with places a 5 day on all deposits.
