I tried to keep to the facts, as given in the Dutch article, but we can all speculate, so let me have a go.
I'm sure (aggressive) marketing plays its part and therefore has some impact but I don't believe that the publicity and hype in respect of TEMPEST were any greater than they were for, say, the previous five Dylan studio albums. TEMPEST got to No.1 in this Dutch chart; the others did not.
It is possible that, in the case of TEMPEST, the "sales competition" was less strong than for the previous releases.
As chart success requires so relatively few sales these days, it doesn't take much for chart positions to change fairly quickly, so it may equally be a question of timing. An album gets released one week and it sales peak as fans buy it but sales soon fall away , just as another artist's album is released and its sales peak, only then to fall away.
Maybe its a question that Dylan fans are older and tend to buy physical albums rather than download them.
Historically, the Dylan albums that sell well do so in the short period after release. In this case, the album was actually sold before release date, got a fairly positive "word of mouth" around fans and record buyers, which may have generated more sales in the pre-release period. Possibly, all those sales got recorded, under the system, in the week immediately following the official relelase date. By this "sleight of hand", sales that might have been spread over a few weeks got concentrated in the week of release, pushing it to the top of the chart. I don't know this but, as I said, I am just speculating.
