Torquetalk,
Please don't misread the chart. The hours column is the pilot's flight time at the time of the accident (for fatals, it is also the maximum flight time, BTW - Duh!). The percent column is the % of all accidents that that hour group experienced. Thus, 15.7% of all accidents involve pilots with 501 to 1000 hours.
At no time does a pilot see a RISE in accident rate at a higher flight experience time, a "fact" that is directly implied by the foolish statement that there are "danger points" at higher hours.
The big percentage of accidents for pilots with more than 4000 hours is because the stats were not run out to big, big numbers at the same granularity as they were for the lesser flight hours.
