Some resistance math

So have a question on resistances. Lets say for arguements sake that I get my ship to 90% resisances across the board for my shields. If another player is rocking a ship that deals 700 DPS does that man that I am only goin to get hit for 70 dmg per second once my resisances are done? If that is the case would having a passive tank of 75 hp/s prevent him from doing dmg to me as I would b able to heal he dmg faster than he could deal it?

In moe specific terms I am looking at the Nighthawk. It has he abiliy to get to 90% resistances across the board and with nothing moe than a few shield puger rigs I get 141 hp/s passive. Does that mean I could take on a ship that does 1410 DPS? (Or two ships that deal 705?)

Remember that each resistance is checked individually and that few entities do strictly a single type of damage. Most do two or three types. Also remember that what's listed is only peak recharge, which happens at around 33% shield. You'll always take some shield damage.

PVP is a question with no single right answer, but a lot of wrong ones.

So the resistance percentage is only when I am at 30% ish? Good to know. Is there anyway to figure out the percentage at full shield?

Not quite, your shield's percentage resistances are there at all times (provided you have cap to power any resistance modules that require cap like invuln fields and DCUs). What Gavin was reminding you of was that in EFT the shield defense amount is only happening at peak shield recharge (which is when you have 25%~35% shields left, just like capacitor). The two are unrelated in any way other than the lower your shield resistances are, the faster they're going to be eaten through, and therefore the faster you will be put past 25%~35% shields, thus negating any recharge much less peak (barring some fits that stack the bejesus out of shield hp).

I am going by the ingame precentages but I think it follows the same rules as EFT.

Is there anyway to do a calculation to get a general idea what I need for regen HP? The ships I am facing off againnst are 750 dps typicaly. I have 90% resists across the board.

No there isn't.

Usually it is best to see how many ships are there, doing that much DPS, then work how your EHP number (shield amount divided by incoming DPS minus 90%).

The regen curve is ALWAYS the same, with peak recharge at about 33% as stated. You can ajust the height of the regen graph by adding shield power relays, shield rechargers, or Purger rigs. Or you can increase the length of the graph by adding extender rigs, PDUs or shield extenders.

Generally, adding more shield is better than adding more regen.

Remember though, EFT has a big fault with this type of calculations: it is assuming incoming DPS is in a constant, steady stream. Instead it comes in steps. That can adversely affect the regen numbers, so always budget for more than what EFT says.

Now when i say it comes in steps, it means volleys. So if a BS does say 2000 alpha, but only 750 DPS, then your regen curve will be hit by groups of 200 damage every few seconds

also remember that if your opponent realizes that you're passive regen tanked they can very easily overheat at the 35% and beat your regen curve.
