Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

Peleton magazine have made a comparison experiment with the Campag EPS and Shimano Di2.

Gave it to Scherrit as I reckon he might find it interesting but here's the interesting part.

SRAM Red downshift quicker than both EPS and Di2 something like 1.25 second compare to campag/Di2 1.8-2second.

Aren't these kind of comparisons a bit useless? How well a drivetrain works is decided by one major factor- the skill of the person setting it up? I'd wager a race mechanic could get Veloce working better than you or I could get SRAM red to work.
