Bonds for Dummies: What does "submitted to accepted" mean?

I read an article on Treasury issuance and they discussed a metric called "submitted to accepted."

What does this mean?
Can you refer me to a book/site/etc?

 

i only trade stocks so this may not be entirely correct.

as an example, if one went Long TLT last week and held then by Friday close he was ready to bend over and accept his fate.
