you seem to be off. by a factor of 10. or did i miss something?

Yes, you missed the number of GBS cases that occur regardless of vaccination.
You also missed the ongoing study by Schonberger . . . in 1982 (after the 1979 study you cited) which found
These results suggest that there was no increased risk of acquiring GBS associated with the influenza vaccines administered during these seasons and that the causative "trigger agent" in the A/New Jersey (swine) influenza vaccine administered in 1976 has not been present in subsequent influenza vaccine preparations.
There was a slight increased risk of GBS as a result of a specific vaccine (A/New Jersey) in 1976, but not to that degree since.
