It is quite exact. Single elemental advantage gives your knight wearing the armor an attack that is exactly 1.5x stronger. An elemental disadvantage does the same to the attack of your opponent. Dual elemental advantage makes your attack 2x stronger.

In your case you should not look at just the armor stats but to the total stats of the knight wearing it. That will be about 300 more depending on your level and which knight you choose. Assuming your did that you can just multiply attack and defense according to what I said. Elemental advantage means multiply your attack by 1.5. Elemental disadvantage means multiply your defense with 2/3 (1/1.5).

Effectively against Razorwind Elemental for comparison adjust stats to:
 * Glacius (single strong) att 1575 def 1050
 * Drake (neutral) att 1139 def 918
 * Typhoon (single weak) att 1464 def 875
 * Demons (neutral) 836/1042
 * Bear (single strong) 1007/528
 * Nian (single weak) 955/813

Remember I just multiplied the stats you gave with the factors. That is the wrong way to do it. Look what the stats are on your knight and multiply those figures.
