Six-monthly progress report

摘要

I'm beginning to wonder whether adding Technical Incidents per 100,000 miles to the table was such a good idea after all. Even when a fleet has to score under five to be borderline respectable, there are some depressingly large numbers as you go down the table. On the other hand, it provides a more direct overview than comparing Miles perTechnical Incident. But begone dull care. For this month I thought I would see if I could find some good news. A fair criticism of TIN-watch is that, while it provides a monthly snapshot of fleet reliability, to find out whether performance is improving you need to get out the back numbers. September's search for bathtub curves showed the best fleets were indeed getting better but covered only selected cases from the five manufacturers.
