Tablets

I'm wondering about, for tablets that increase stats for durability items...
what's their succession rate?
It says they go down, so is it like equip enhance scrolls?

I forgot the exact % but it's something like

70, 50, 36, 26, 19, 14, 10

And the boom rate is in reverse

That's more or less what cyanne said, so im assuming the boom rate is 10, 14, 19, 26, 36, 50, 70 if you fail it.

ok thanks.
