@mathil: The H2O (first of its name) (and possibly other Mark5 devices) is a special snowflake in that its CPU frequency scaling is completely bonkers, so it's kind of a terrible (and, most importantly, unreliable, since I couldn't find rhyme nor reason to its scaling behavior) benchmark to begin with
.
@koboy: I'm sure @davidfor could expand on that, but, in short: no.
