There's adaptive time stepping, but that may be too slow to react to very rapid changes. It's probably safer to up to 0.11s with a fixed step, save and then continue with a smaller time step. Autosave is a very useful feature too.  However, getting to 0.1s in 800 iterations may mean you need a smaller timestep to begin with.
