What is the expected output? What do you see instead?

I don't expect to see Strength contributing to TMI at the rate demonstrated.  

It is practically as good as parry/dodge and as far as I can see it should only contribute
to TMI at the rate it converts to Parry.  What am I missing?

Also, the margin of error on the TMI weights is huge.  Any tips on how to narrow this?
 Does it have more to do with the range of TMI values or the number of iterations?

I'm not sure what the concern is.  Here's the stat weights from the attached html file:

Stat   Scale Factor
Str     -0.69
Sta     -1.55
Exp     -1.39
Crit    -0.45
Haste   -0.03   
Mastery -1.30
Armor   -0.80
Dodge   -0.80
Parry   -0.92

From this, strength is actually less effective than dodge or parry, not more.  And
remember that every point of strength gives approximately 1 parry rating worth of parry,
so they should be pretty close.

More importantly, the uncertainties in that report are +/- 0.45, which means you can't
really say anything significant about the relative worth of strength, dodge, and parry.
 Within experimental uncertainty, they're all identical.

Ok, I had it my head that the Str didn't convert into Parry at 1:1 so that makes sense.
 Can you give any pointers to reduce the margin of error?  Just throw more iterations
at it?

[navv1234]

Pretty much.  10k is usually pretty good for paladins, but it may take more iterations
for warriors.

I just ran the profile with 500k iterations. Results are pretty reasonable (error +-
0.05_

Str Agi Sta AP  Exp InvExp  Hit Crit    Haste   Mastery Wdps    Armor   Dodge   Parry   BlockR
Scale Factors   -0.46   0.00    -1.35   0.00    -1.87   0.00    0.00    -0.26   -0.00   -0.95   0.00    -0.70   -0.67   -0.68   0.00

I just ran the profile with 50k iterations making just these one change to drop some
hit (but still over cap)

reforge hit to dodge on the waist

everything looked good except Hit which had values all over the place and ended up
with a value 15x larger than any other stat with a margin of error twice as big as
the bar itself.  Does this sound like normal behavior for a stat with a hardcap?

yea. hit calc can be buggy depending on how far it is over cap.
