If I remember correctly, you changed the timestep while the simulation was paused in the previous version's tutorial. I think that was better, I think you get a little bit stress when the system begins to interact in the high timestep.
At least I do because I know things will be flung far away probably because of inaccuracy, but new users probably wouldn't think that. Or perhaps other users don't care about it at all?
On the other side, you can see the effect instantly, which is good.
