Dragoons: A Rotation Reborn

[zeth07]

Random question about using the spreadsheet solver:

I'm solving for 495acc with what I have and I'm using the "Compare Score Against" while setting each individual Soldiery piece to see how much it would change. So by default the difference is 0 with the initial armor setup I'm using. Then I enabled the Weathered Gloam Choker and reran the solver and it ended up having a difference of +0.371.....but didn't use the choker and ended up changing other pieces.

Why would it do this? Other pieces show an obvious increase by using the new enabled item, others show no difference by not including the item. But this one shows an increase, but changes items that were already available and not the new item so why wouldn't it use that setup as "default"?

Default Setup = Solved for 495 ACC:
Wave Harpoon
Wyrm's Armet
Wyrm's Mail
Allagan Gloves
Allagan Waist
Weathered Astrum Hose
Wyrm Greaves
Hero's Necklace
Allagan Earrings Maiming
Hero's Bracelet
Allagan Ring of Striking
Weathered Gloam Ring
=696.087, 496 acc, 419 crit, 319 det, 404 speed

Enabled Weathered Gloam Choker (but it isn't selected in the decision variables):
Changes To = Hero's Belt and Allagan Ring of Maiming, the rest are the same.
=696.458, 496 acc 430 crit, 322 det, 388 speed
