With the "March 15 entry being in error" scenario the rods were submitted at 9:45 pm on March 23 and then released at 7:50 the next morning.

It's not just a "March 15 entry being in error" scenario, it's a "March 15 entry being in error; 9.45 am entry being in error; Lieutenant Day being a moron; Agent Howlett not noticing that Lieutenant Day was a moron; Agent Howlett being a moron for thinking a test for Oswald's prints would prove anything remotely pertinent to the case" scenario!
In short----a wild and rather desperate speculation in defence of your beloved "Oswald being a Lone Nut Presidential assassin" scenario!
