Can anyone give me a Least Mean Square version of the following scale?

"Addenda (Mike's 7-limit-dyad-focused scale)"

1
172.85564
434.12203
609.14048
701.955
876.741864
1093.7998186

   Note: this tuning is designed to use a whole lot of 7-limit the the 7/6, 12/7...7/5 and 10/7.  My Infinity tuning has that weak point...it's focused more around either meantone or Mohajira-type intervals with a little 7-limit...this scale is designed to have a lot of 7-limit and some meantone-type intervals with a few Mohajira-style ones.

  The result is a scale that, hopefully, will sound very xenharmonic to a whole lot of people, but doesn't have many weird fifths (there are only two Mohajira-style 22/15 diminished fifths) or 9 and 11 limit
intervals...plus the only "non just/off" intervals include one near the 12TET major 7th and Minor 12TET minor 7th IE "wrong, but familiar" intervals.  So it should hopefully sound oddly stable to a lot of people.  Any general thoughts/impressions/ideas/suggestions for this scale?

What tuning accuracy were you wanting? Below I use 10 cents.

   10 cents isn't bad, but 8.00 cents maximum would be nice if you can get it...

   Come to think of it, having a 14-cent max version would be interesting as well as an 8 cent max version... 

   There are two dyads that are a bit weird in the 10-cent lesfip scale...a diminished fifth near 16/11 (much harsher sounding than near 22/15) and a "major 4th" near 21/16 instead of 4/3.  I'm wondering if a 14-cent lesfip or an 8-cent lesfip would/could fix either of those.  Other than that...virtually everything looks great.

I think what I gave falls well within that bound. Ten cents is just the cutoff I used.
