I need help understanding Wrathful Advance's flat damage bonus

I would like to subsume this ability for another frame I have. I know it's capped to 100% if I do so.

So on the wiki it says

The final critical chance applied to melee weapons is a flat value applied after mods (e.g. a melee weapon with 25% critical chance becomes 225% when a rank 3 Wrathful Advance is active).

Let's assume that I have no other buffs to critical chance for a weapon that has a base 10% crit chance. That means I would have a 110% crit chance on that weapon.

But I've seen several people saying that this ability scales with Strength. So if I have 150% strength, I take 100% of that 150% and add it to my base. So I would have a 160% crit chance.

This leaves me confused. I just want to know what is the correct method of calculating crit %.

Thank you in advance.
