This does not seem very likely. I just don't see 26.7% Dutch contributors on the Danish Wikipedia. Who are they?
Even if you did include some interwiki link robot in the statistics, 26.7% of all contributions (or contributors?) seems far too much.
That users in Belgium are split between French and Dutch is the nature of this country. Belgium originates 1.8% of all contributions, which is also reasonable.
It's the number of users from the Netherlands that are far too many, 6.1% of all contributors, ranking as the 4th contributor country. They should rank lower then contributors from France (5.6%) and closer to Belgium. Perhaps they should be half their present number (3.1%).
I guess the odd statistics could be explained by some major ISP (UPC/Chello?) reporting their entire European network to be located in the Netherlands. Did you check this?
Assuming that half of the reported number are real Dutchmen, that would put their contributions 66% in the Dutch Wikipedia, 25% in the English Wikipedia, and 9% in other places. The other half of the alleged Dutchmen could be equally distributed among other European countries. The reported Dutch contributions to other languages could be moved to each native country, thus the Danish Wikipedia would have 54.8 + 26.7 = 81.5% contributions from Denmark. That makes more sense.
You need to fix the error in the geolocation database, or to exclude the IP addresses that you fail to locate correctly. Alternatively, you could count the problematic ISP as a virtual country of its own. Just don't count them as Dutch people.
