The number of users that drop-off at each stage will be really useful. Would it be possible to get the information in such a way that we could also check how long each step takes? In that way we could get an idea of how much time on average a user spends on each step and in total, even if they succeeded in the process.

Logging the time from a successful step to the next successful step is easy. Logging the time from a successful step to a failed step (i.e. the user leaving) is possible, but what Gilles said applies (we have to discard some browsers).
