I guess it's not clear what problem you are trying to solve.

Dear Peter,

I'm trying to balance the original problem statement (protection from
users enumeration) and avoid doubling time here if the process has
already taken a long time to provide faster auth method iteration.
I believe that a better solution is to set some arbitrary (probably
configurable) timeout and, in case when we spend more time than that
value, avoid doubling it.
