Ah, you are correct. IIRC the French study was a single sample.

On the other hand, I feel 98 indicates a wide spread in Norway and probably in whole Europe. But that doesn't match the picture we had in EU around January-February.

This is an insane proportion and the virus would have been picked up much earlier in a place like Norway which does lots of testing and flu sampling.
