Back to back similar midday. I've already been experimenting with one number ups/downs but I'm seeing situations where flips need to be considered.

 

 

If I had brought back the 1 and one number upped the 8 and one number downed the 28 and flipped the 12 to 21, I could have gotten four numbers midday today. 

 

1-9-19-21-27

 

 

I would have had an issue with 9-19 in the past not to mention 9-19-29-X-X because I had this thing about more than one number ending with the same number. I just didn't like how it looked and it just felt unlikely. I now have accepted that a number is just a number and any number can be sucked up.
