I was asked this question today. The weapon being discussed was the Omegaton L1010(L) so I will use it in this example. They said they always buy the cheapest one in auction for around 111peds. (its 88peds tt so I did the math backwards to figure out that is around 126%) Here is a chart comparing the Damage per PEC and Damage per second for this gun unamped and with the A102-A106 as well as A204 amplifiers. (make sure you understand that these numbers are assuming that you are maxed (SIB = NOT ANYMORE) for both HIT and DMG professions on the gun) Using the A102 amplifier you would get 2.851 dmg/pec and 38.40 dmg/sec Using the A104 amplifier you would get 2.890 dmg/pec and 43.67 dmg/sec This means that the A104 provides 1.368% more dmg/pec than if using the A102 on this weapon. This means that the A104 provides 13.724% more dmg/sec than if using the A102 on this weapon. Almost 14% more damage a second means that much savings on your armor and fap because the animal is attacking you less. It also means that the animal will regenerate less health before you kill it due to your kill speed. Both of these will provide you with significant savings over time. Now lets talk about the 1.368% damage per pec increase. It doesn't sound like a lot, but let me show you how fast it adds up. 1.368% for each 250ped hunt = 3.42ped savings (or 3.42ped more animals killed depending on how you want to look at it) Suppose you go on 4 hunts that size a day. 13.68ped saved per day 95.76ped saved per week 410.04ped saved per month 4993.20ped saved per year Now just for fun, lets compare it to the A204 amplifier :) Using the A102 amplifier you would get 2.851 dmg/pec and 38.40 dmg/sec Using the A204 amplifier you would get 2.922 dmg/pec and 48.19 dmg/sec This means that the A204 provides 2.49% more dmg/pec than if using the A102 on this weapon. This means that the A204 provides 25.495% more dmg/sec than if using the A102 on this weapon. Savings on the same size hunts, 6.225ped saved per 250ped hunt 24.90ped saved per day (4x 250ped hunts) 174.30ped saved per week 747.00ped saved per month 9088.50ped saved per year Sometimes it can be more economical to have higher dps and lower dmg/pec if combating animals with high regen or that hit hard/fast enough to incur high defense bills. But in the case of the Axxx series amplifiers its always more eco and more dps to go with the largest you can fit on your weapon. Remember though, an amplifier can only add 50% damage to the base value of the weapon it is attached to. So don't try putting a 12 damage amplifier on a 18 damage gun since the most it can utilize would be an extra 9dmg amplified.
