It does say that they cant give a time or guarantee.
That post by Auto was designed to give a personal opinion based on experiance done to help ppl - yet in your previous post you claimed it was insuffiecent - "Though this response answers the question, it does so quite badly"
That is why you have got ppls back up a bit in here - someone trys to help thens gets slammed for it.
Of course you have brought up an issue about lack of info that can confuse newbies - so maybe now your initial question has been answered you could create a new thread in chit chat - detailing your suggestions for improvements google can make to the submission section?
Googlers often read the posts here so maybe they will take your suggestions on board.
