Hmm - I didn't try and make it go up to more than 850 
I just asked it to simulate best action, and it gave me:
Best Action - Pay Down 90%-100% of Your Credit Card Balances - Over the Next 24 Months
814 - 850
Paying to zero util does not give me the 850, and paying bills on time for 24 months does not give me the 850. So it is zero utilization and 24 months history at that for perfection.

Just maybe some of us will hit 850 then in the next 12-24 months! We shall have to wait and find out. Congrats on your credit perfection skills.
Looking at all 6 scores (self and DW), I am guessing you can't get it to estimate the 850 until the score is currently over 800.
I've seen other score predictions with less spread. Yours shows a 36 point spread. I've seen other with a 30 and 20 point spread. Maybe you've got what it takes and age is holding back and maybe inquiries, and little green boxes.

Has anyone using the ScoreWatch calculator had their 24 month range between XXX-850?
Mine only gives the range 817-847 over the next 24 months
Guess I'll always be a day late and 3 pts short

Do you have new accounts less than 12 months?
Yes.
But the age is very good, and this report has no boxes any color other than green
