No.
I cannot find a single imaginary (or real and potential) emergency which a Dive Computer/Bottom Timer could have prevented or resolved that dive that day.
That is why we are still discussing this thread best summarised here:
Bottom line - you are using this thread to attack me personally - why?
Bottom line is you broke standards and limited yourself options if an unforeseen event had occurred and you play it off as something that should be accepted by the community as acceptable. This is a public forum and if you are going to go on the record as saying it's ok to break standards and not follow common protocol I'm going to call you on it so those aspiring to dive at your level in the future use you as an example of what not to be like as opposed to to hoping they can cut corners like you do.
You can try to convince the internet you were right as much as you like. I think your whole story is contrived and given that you won't lend any technical information on the dive site for others to critique I'm resigned to believe that you made the whole thing up much like many of your comments in other threads. You can't speak with an air of authority and then be so damned conflicted without people sitting up and calling you on what they consider complete bovine feces.
