You do realize that even after reading those graphs that there is a point where regeneration is best mixed in, right?
Also, it really isn’t worth much, that extra 30. I’ve read those charts before, and I know them well enough to know that there is enough defense already by using other methods and just the base defense itself.
If an enemy has 3000k damage, and I halve that by 50%, that’s 1500 damage per second. If I regenerate 423 per second, that’s almost 1/3rd of the new damage. Now this enemy is hitting at 1,077 dps. I can further use the shield booster L to bring that even closer to 0. With the every now’n then boost from the emergency and multiphase or signature masking, that number becomes a most satisfying 0 damage. The base shield regeneration ensures that the modules need not be used excessively, and will be used only when they are truly needed. This doesn’t take into account that the enemy is likely dead within a few moments. 2 enemies hitting at 3k ps? it’ll be like only 1 guy is hitting you, and sometimes not even that. 3 guys? well, then we’re getting into where it depends on your positioning. Of course there are always those dps builds, but that’s where skill comes into play. Everything has its limits. Fight alongside a healer, and you’ll be all the better while stacking your shield regen with the engineer’s healing modules.
If I’m using signature masking at 19.9% reduction, the 1,077 becomes 862.677.
Feel free to fight alongside a command if you want to stack your base defense.
To note, I haven’t been taking into account the -30% special project frigate auto damage reduction. 
862.677 becomes - 603.8739 ps.
A single shield booster L will take care of that, for the most part.
The base shield regeneration is also usable outside of battle unlike the pure tank types. The regenerative types don’t have to waste their regeneration modules in this time and they can save them for the battles to come.
My math isn’t perfect, but there it is, the gist of it.
Your rebuttal is invalid.
Also, pure tanks are simply waiting for an ecm or command to cancel out their precious modules. At least the regenerative type has one that can’t be shut down. Energy is never a problem with the 7c implant.
