That's not enough to explain everything we're seeing though. For example, why is EFT reporting 356/second shield regen for his fit? Is that from a shield transporter? Or is EFT making up some sort of inferred effective regeneration based on something? I notice that when dragonshardz plugged it in, it looks like EFT is reporting different regeneration rates based on whether or not hardeners are active. 46.6/sec with them off vs 119/sec with them on. Sounds to me like EFT is using the same words to mean something very different than they do in-game.
You're still failing to read and understand.
I could say don't call me an asshole for pointing out you don't understand how EHP works and displays in game vs actual performance. 10-20% resist difference is your problem. EFT victory.
Eve client shows your worst resist as EHP. EFT shows your average resist EHP, or you can change it to display based on damage types.
Because resists/EHP is different, you'll be able to tank a different amount of shield regen for different damage types.
The Eve client only shows the worst one and lowest EHP.
Let me make it simple- here's the tengu fit with one OGB:
Eve client only shows you the absolute worst EHP you could have. Notice that 153339 EHP with 196 ehp shield/sec is a lot different from 394468 EHP with 490 ehp shield/second.
Your Eve client would report 153339 EHP. EFT tells you the average EHP across all damage types on the main screen, since EHP always changes based on damage type.
What this means is, unless you are unlucky to be hit by the one damage type that maxes damage against your resists or you're dumb enough to fly into it, your EHP will always be quite higher than what the Eve client says.
EFT will give you the perfect numbers when you set it up correctly, as shown above.
EDIT: Don't put words in my mouth, Lord Bucket, I never called anyone an idiot. I said you don't know what you're talking about, and it's obvious that you don't know how the EHP screen works - and you called me an asshole for pointing it out. I even said I messed up because I saw the unactivated damage control and I assumed that the other modules were unactivated.
Just admit when you're wrong or don't understand. Don't attack people for pointing out that it isn't right.
