Sending returns in before Jan 28th and Feb 11th only makes them sit at Intuit

(and locks you out of them if a client comes in and says "Oh wait, this just arrived, I forgot about it", then youre stuck having to amend later once the 1040X forms get finalized usually at the end of February/beginning of March),

they'll be sent to IRS in the same traffic jam as everyone else on the 12th.

I always wait 3 days after opening day to send any of my clients returns in...I want no part of that opening day mess.
