So? Why can't you make the next logical step? If it's a 17% increase for Switzerland, then it will be at in the same ballpark much for all other countries, won't it? Then an increase for Germany will be probably as much as two Switzerlands etc.

Ah yes. It's just such an easy not an egineering challenge to do.
