For every revision i do receive i fail to receive the previous one. i.e. just received revision 14 but have not yet received revision 13 and this is not the first time. Had previously sent email about this to Jeppesen and they promptly couriered out the missing updates. Why dont they just courier out the revisions rather than use standard post? That way we should (technically) receive the updates on time - especially for us living in remote areas... yes yes i know, it would cost Jeppesen a fair bit to use couriers, but hey.. we pay quite a bit for the service ourselves..
