    Yes, it means that recount may return a higher value but it is never
    lower.

    I think it should be safe though as recount is not always called (it is
    only called if the phys/hw segments exceed the limits). In the cases
    where it is not called you may be looking at an overestimate anyway.

    Thanks,
