Hi Ben!

Thanks for your report Steffen. Nice to see such comparisons even when a
bit apples & oranges.
Will you be implementing those "additional verification and normalization
steps" ?
It seems they have an exponential or power impact on times.

I certainly will. Meanwhile, I have some more precise numbers. As it turns out, it is indeed the additional steps (nobuild) that causes the impact. I also added the (nobuild) times from another tool, the probabilistic model checker Storm.
