1- AeroGut- You have it backwards. Current SIS spec cable casing is considered by most all (manufactures included) as the compressionless type. It's more linear spiral of the casing strands are more able to resist compression. The common brake casing uses a spiral winding with more flexibility at the expense of more compression.
2- There have been a number of published attempts to measure lever and caliper mechanical leverage, cable travel and total system "power". John Schubert was the first in my biking like to do this in the late 1970s/early 1980s for bicycling Mag (and was it also for Bike World before too?). It's not hard to do so, just a lot of work and no one wants to pay for it. Andy
