It became official a few minutes ahead of my post.
One may also wish to consider that Estonia as a country has a population of less than 1.4 million.
Right. But again. Don't underestimate the Russian population living to the East of Estonia. The same way Russians fly from Tampere (the distance from St. Petersburg to Tampere is as much as 470 km), they'll be flying from Tallinn too (360km). Only Lappeenranta is located better (195 km), but here FR is slower to develop.
The distance is a very relative concept, I would say.
