Hiya,
well, yes. It only reaches 20%-30% for me, but that might be because I have a stronger box

Thing is, that's about the same I get when turning pages, thus that's perfectly normal and to
be expected (because basically it
is a page drag, just an automatic one).
Could you check what load you get when flipping or dragging pages? If that's noticeable lower
then something is weird indeed. But I have no idea what might be...
