I know your local water is warm like here, but 8 hours is really pushing it especially if the previous hours involved hard work, or it just happens that you have to work hard on your 7th or 8th hour.
I am guiltly for pushing the CK scrubber in the first few years as well (i.e. curious about the limit) so can't speak too loud, but be careful and should be prepared to go off the loop as effectively as possible - if you need to.
