ION Stage I: what would you do differently?

[ijmorlan]

Searching online, it looks like most Flexity models are rated for either 1.2 or 1.3 m/s².

They are capable of doing that, but do they do it? The app on my phone that I've used to track speeds has never shown more than a 0.4m/s² acceleration.

1) I wouldn’t trust a phone app to capture instantaneous acceleration very well.

2) Proposed service improvements can take into account the capability of the system even if current operations don’t take advantage of those capabilities. For example, maybe they only accelerate at that rate because they know the signal won’t trigger in time if they go faster, so no point in punching it only to slow down a moment later. But in that scenario the fix is to improve the signalling system.
