Depends how long your after-update tutorial is. We ran an A/B test on some 3-pane and 8-pane versions of these at my last job and on the long ones with a "dismiss" button IIRC it took our users something like 3.4 panes to hit it on average. The long ones without the dismiss button got people to view panes 7 and 8 a lot more often but there was a noticeable (albeit small) uptick in users who left the site entirely instead of finishing.
