Ok. Possibly a shoot me question since I've been a PLD main for so, so, so long but I just can't find any of the specific information I'm looking for.
When it comes to shield blocks we all know the following:
Size 1: Low damage + highest activation rate
Size 2: Slightly higher damage + lower activation rate
Size 3: Most common and ideal shield - good balance of damage + can still cap rate
Size 4: Highest damage absorbed and lowest proc rate.
Let's ignore aegis for the purposes of this question and for the purposes of the description let's just assume 0 shield skill gear / merits so it actually makes sense.
My big question is regarding all shields, although specifically for size 3's, how does 1 base defense added to the shield translate into damage mitigated?
For example: Koenig is DEF22 and Kaiser is 23. Assuming a shield block with Koenig will get you hit for 50 damage will Kaiser lower it to 49? 48? 45? 50 - x? Original damage - DEF x static reduction %? (That last one may not be as clear as it sounds to me)
The point of the question is obviously to help PLDs when /WAR or /RDM or in certain situations /NIN to make the best choice for their situation. Terror shield, for instance, is a very good shield but has a DEF rating of 20, which is 9.x% less than Koenig - how will this translate to damage mitigated?

Supplementary questions:
-- We all know how fSTR correlates to weapon base damage for the purposes of melee - perhaps there is a VIT or DEF modifier that will apply to shield? I find this unlikely but is it worth exploring?
-- In terms of potential damage mitigation is there a cap for each shield size? I.E. Can a simba buckler (size 1 DEF24) ever reduce as much damage as Koenig (size 3 DEF22) under specific conditions?

I know I'm asking a lot of questions without providing much but I don't recall ever seeing extensive testing on any of these areas and search has failed me. With all the attention we pay daily to min/maxing for melee I feel I've neglected my PLD/RDM, which remains one of my favorite job combos to play and I know many people feel the same.
