I haven't really done any extensive testing, but just standing around at Warrior Grounds, I take about 69x~9xx damage from their magic attack with no charges, and it seems to lower to 5xx~7xx with all 5 charges (possibly unnecessary, I doubt I have that much more than 9999 MDEF). The 9999 DEF/MDEF cap could possibly just be visual.
If damage reduction from DEF is still calculated as it was during Big Bang, then the jump from 9999 (~50%) to 19999 (~71%) DEF/MDEF would result in you taking ~72% less damage.
