The Legend: Tenacity runes doesn't work properly

If you buy Merc Treads and fully stack this rune it only gives you 44% total tenacity, instead of the expected 50%.

Fully stacked rune = 20% tenacity

Merc Treads = 30% tenacity

Rune+boots=44%?

I'm not good at math, but something's not right here, tenacity is already a bad stat overall with the overabundance of displacements and knockups, why should it's rune also be trash?

EDIT: So it turns out it stacks multiplicatively instead of additively. Every other stat in the game is added instead of multiplied, and getting "20% tenacity" and "30% tenacity" is instead multiplied. Such a trash stat.

The CC get's effected by one and then the other, not both together. It's multiplicative, not additive.

If tenacity stacked additively then both DrMundo and Garen will have 100% tenacity almost all the time.

Mundo could have

W= 30% item 3111 =30% item 2138 25% The new rune = 20%

total 105%

now do you see why it can't be additive?

Edit: I forgot item 3053 when popped is 30%. So this on other melees can have 105% like mundo for 8 seconds.

That may not be because the math is wrong. The actual value you end up with depends on how it’s added. If it stacks additively, then yes, something’s not right. If it stacks multiplactively, then that may still be correct.

separate sources of tenacity have always stacked multiplicatively.
