I wouldnt mind that much if it wasnt perfect. If it would be easier to go to the next new post and instead of recalculating all the pages (that as you seem to say would take much resources...) just grab the 2 earlier posts and start building the pages from there, backwards and forwards, even if the previous page had only 6 replies I´d do it. Maybe others would not like this and preffer it as it is now, but I´d personally preffer that, its a time saver.
