How come rbt's trade fair expert Scharfie hasn't yet gotten ahold of a Neco

Looking at the graph in Fig 13, 16 kph produces 1 to 3.5 watts. What's
different is that this dynamo does not saturate and continutes to
produce higher power output when spun faster.

If my German is still functional, Fig 4 says in the caption 15 watts
at 12 km/h. However, the English language text in Fig 4 says "With
riding speeds up to 12 km/h... can supply 0.5 to 2.5A. That makes no
sense and contradicts the numbers from Fig 13.
