Ok from a quick screwing around in Altepa...
When muppet hume was in range as well (I was trying to heel/stay Carrie in the right place) 333(me)/333(Lusien's Carrie - 76 BST)/317(Cesaria's Carrie - 78 BST)
Straight split 1k needles - Cesaria's Carrie (has job trait at lvl 78) 476/Lusien's Carrie (no job trait as he's 76) 500 damage
Husband who's mathematically minded says that's just a smidgen under 5% damage reduction. Will muck around more with it later but neither character had any pet damage down gear equipped, I called Carrie without AF2 hands on both chars, the only difference merit wise is I have BST affinity merited a couple of levels on Ces.
Basically I set Carrie on a cactuar, let it knock it to under 20%, heel/stay/snarled it and heeled both Carries to be the only ones in range and then fed TP via dia spam/snarling hate off.
Hope that helps someone.
