Magic Accuracy

I'd go for a more conservative:
macc = A*level + B*DEX + C*LUK + D*INT + E*GearAcc

I put that, omitting the GearAcc, in some Maricies on my TI83 and got a value of 1 for each variable, A~D. Tried to put GearAcc into it and it's giving me "SINGULAR MAT" error. :|

The only problem I have with a flat addition is the lack of change in Accuracy when I level. I'll go level a few times and see what happens.

Edit: Then Stereo comes out of nowhere and ninjas me. :|

0.5 * dex + 1.25 * int + 1 * luk + acc

Rounded to the nearest point, fits everything posted.

Do we know the Physical Accuracy Formula? If I were a dev, I would swap INT and DEX, remove INT in that formula, and call it done.

Pretty format:
Phys Acc = 1.25 * Dex + LUK + Acc


Added a lv 15 test on snakes.

Edit:
Added 2 lv 17 Test.

Edit2:

With +2 Dex
Without +2 Dex

If Stereo's formula is accurate, shouldn't there be a difference in accuracy between the two SS?
