Biological Oxygen Demand ....

Hi,
So in my trial I accidentally put the days required to leave the water sample for biological oxygen demand measurement as six days instead of five.  I got marked down one mark in like a 6 marker because of this - and my teacher said that she used to teach it as 5-7 days....

So if I can find a source that says like it requires six days or five to seven, I can get a whole extra mark - which would be pretty significant cuz I kinda didn't do all that great.... But I'm kinda struggling to find anything....

If anyone has seen a source that says BOD requires 5-7 or six  days - that would help me out heaps.
Thanks! :)
