I might be misunderstanding something due to the language difference here, but when I check the mentioned profile stats I'm seeing:
Floh1967: 1809 finds in Braunschweig, 157%
GeoTschorny: 1735 finds in Braunschweig, 151%
So apart from the numbers looking correct we can determine that 1% will be around 11.5 caches in this area which means that a difference of 3 finds would likely just round to the same percentages anyway.
