AR and Defense of Druid Minion?

[Eradan]

My Teory (all tested) disprove if anybody can.
Attack Ratung. For Raven, Spirit Wplf, Dire Wolf, Grizzly.
AR=X*K1(monlvl.txt)+A1(monstat.txt)+A2(skills.txt)+A3Passive(skills.txt).
Where:

A1 from file monstat.txt column A1TH, A1TH(N), A1TH(H)
0 - Raven
50 - Spirit Wolf
150 - Dire Wolf
300 - Grizzly

A2=K2+K3*(lvl-1);
Where k2 from skills.txt column ToHit
k3 from skills.txt column LevToHit
lvl - level of skill.
_k2_ _k3_ _summon
100_ _15_ _ Raven
_75_ _20_ _Spirit Wolf
150_ _20_ _Dire Wolf
300_ _20_ _Grizzly

A3Passive=K4+K5*(lvl-1);
Attention: it is passive bonus from skill Summon Spirit Wolf(not for Raven), but not % is +AR.
K4=50;
K5=25;
lvl - level of skill Summon Spirit Wolf

K1 - coefficient from monlvl.txt (dependence from difficulty and druid level)
X - only test result= 80+-10. (I don't know exact).

Example. Druid 80 lvl on Hell difficulty. Raven-2 level. Summon Spirit Wolf - 10 level. Summon Dire Wolf - 10 level. Summon Grizzly - 10 level.
Raven AR=2689
Spirit Wolf AR=3154
Dire Wolf AR=3329
Grizzly AR=3629
