So it seems like you're saying that if you already have a 50% reduction, getting to 75% will halve the damage you're already taking. Which is to say, moving from 50% to 75% damage reduction will double your survivability. Sounds right!

But it's worth noting that getting from 50% to 75% is quite the undertaking. It takes 300 armor for 50% reduction, but then to get that to 75% it takes 900. So doubling your survivability requires 3x your armor. To double your survivability from there, you need to get to 87.5% reduction, which requires 2100 armor, or 2.3x the armor. And while it's basically not a real scenario in the game, going from 0% damage reduction (100% damage) to 50% damage reduction (50% damage) isn't even possible via multiplication, since 0% reduction is 0 armor and multipling 0 isn't going to get you anywhere. Mathematically I guess that's infinity?

From that pattern, we can determine that the amount you need to multiply your total armor value by to get the same amount of "further damage reduction" seems to decrease as your damage reduction rises. However, since it will always cost more points of armor to hit the next threshold (which is to say, the number you need to multiply by never dips below 1.0), it's worth clarifying that this is still diminishing returns.
