Today I will be looking at the Real HP of the Gallente Sentinel With all skills maxed, on a tanked suit (only
plates and extenders).
TL;DR at bottom
Gallente Tanked suit
Base armor = 525
Armor bonus from upgrades skill, (525 x 25%) = 131.25 (132)
Base Shield = 390
Shield bonus from upgrades skill, (390 x 25%) = 97.5 (98)

4x complex plates @ 135hp ea. = 540 armor
Armor bonus from Plating skill, (540 x 10%) = 54 armor

1x complex extender @ 66hp = 66 shield
Shield bonus from Extender skill, (66 x 10%) = 6.6 shield (7)

Total hps
Armor = 132 + 525 + 540 + 54 = 1251
Shield = 98 + 390 + 66 + 7 = 561

Effective HP vs. Differient weapon types.
Note: Resistances are calculates by dividing the base by ( 100 - resistance value). This is how it is done
look it up.

Explosives (splash)
-Armor
25% reduction from sentinal skill - 20% armor weakness to explosive = 5% bonus
(1251 / 0.95) = 1316.8 (1317)
-Sheild
25% reduction from sentinal skill + 20% explosive weakness to armor = 45% bonus
(561 / 0.55) = 1020
Effective HP vs Explosives = 2337hp

Hybrid - RailGun
-Armor
15% reduction from Skill Bonus - 10% armor weakness to hybrid = 5% bonus
(1251 / 0.95) = 1316.8 (1317)
-Shield
10% hybrid weakness to shield = 10% bonus
(516 / 0.90) = 573.3 (574)
Effective HP vs. Hybrid - Railgun = 1891hp

Hybrid - Plasma
-Armor
10% Hybrid weakness to armor = 10% bonus
(1251 / 0.9) = 1390

(561 / 1.1) = 510
Effective HP vs. Hybrid - Plasma = 1900

Projectile
-Armor
10% Armor weakness to projectile - 10% bonus from skills = 0% weakness , 0% bonus

(561 / 0.95) = 590.5 (591)
Effective HP vs. Projectile = 1842

Laser
-Armor
20% Laser weakness to armor = 20% bonus
(1251 / 0.80) = 1563.75 (1564)

(561 / 1.2) = 467.5 (468)

TL;DR
Effective Hps

Hybrid - Plasma = 1900
Hybrid - Railgun = 1891
Projectile = 1842
Laser = 2032
Explosive (splash)= 2337
Average of all values = 2000.4 (2001) Effective HP
