The discussions of the Line 6 performance that I see are almost exclusively about the end-to-end time. But for many (maybe most) customers frequency is more important than speed. This is true for those who only stay on the line for a few stations, and for others who prefer sitting on even a slow moving train to a long wait at a station. And by frequency I mean not just the average time interval between trains, but also the worst case interval.
The average interval is determined by the end-to-end time and the number of trains in service. So speeding up end-to-end certainly helps with frequency and is definitely worth doing. But if that is impossible or difficult, frequency can also be improved by buying more trains. Which means money of course, but what doesn't?
The worst case interval is something else. Even if you speed up the end-to-end time to the originally promised benchmarks and thus get the average to be acceptable, the worst case may still be terrible. To optimize the worst case, the operations must prevent bunching and keep the trains evenly spaced. We'll see how that goes; not much has been reported so far.
