Just to clarify for the hard of understanding.....
I wouldn't consider 30hrs excessive as there are any number of reasons progress may be delayed. Long breaks between flights/ weather/issues at home or work/money shportage/chopping and changing between junior instructors/changing schools/ student confidence issues. I've seen most of'em. The point is while 30 hrs is not excessive, it is outside the normal range. So any reasons for this should be investigated. Thats's why we had those points. So things didn't balloon out because of a problem rather than circumstance. The point is it should be looked into but it's not worth an inquisition.
