There are couple of times incorrect bids, within 5 min range or less I typicially let it go... Look at last year's D.Jackson's bid. It was incorrect bid. Miami lost.
Look at Todesco's bid- he lost.
There are couple of time in past where owners type and 1 min later OOPS type correct. I can understand typo sometime happens and correct it. If it was not corrected- it considered a concrete. Its not new...
