Ah wait, it's Gen 1 and Gen 4 that use the 1:1 ratio. Regardless, load and riding conditions/style play a huge factor.
Same deal with brake pads; I get under 1000 km from a full set of Magura quad-piston ones because hard braking with well over 200 kg of rolling weight from high speeds puts huge loads on them. And it's well worth it.
