I was able to get 4.5k ship spins in about 2 minutes. Steps to replicate…
I right clicked and dragged the view offset slightly, then while holding it there, alt-tabbed to another window
When clicking back to the game it held the view, then left dragging to view the ship from the top put it into super-speed ship spinning mode. It would slowdown the counter about every 200 spins but moving the view slightly away, then back again restarted it. Eventually I was able to move it to where it was able to stay put without holding the mouse buttons, putting my tengu into perma ship spin really fast.
