While that is true, all your examples take place AFTER Denmark lost Skane. Until 1645 or so, the Danes seem to have perfectly held their ground.
The question is really, was that loss and thus the subsequent decline rather inevitable, or was it a fluke/lucky roll for Sweden that allowed them to get out of the Sound dues and take important Danish land, allowing them to snowball until Denmark couldn't stop them?
From what I can see Denmark was also fighting other countries in that particular war (namely the Netherlands, who according to wiki provided the bulk of the fleet involved in the decisive naval battles) and so I would see it as 'Sweden in a good spot smacks Denmark in a bad spot, and Denmark never recovers'. If it hadn't won that war, but instead Denmark at some point had found a rich and powerful ally strong enough to help Denmark seize Goteborg or the Swedish baltic provinces...?
