Motty82, what you describe sounds like normal Insight behavior to me, except for the event which Armin referred to as "not something I have seen before." I have also not seen that on my SOC meter. Other than that, my Insight behaves much like yours.
When you do experience a battery state-of-charge recalibration, then you'll get a good sense of what an Insight feels like with no assist... weak!
