My understanding is that when you create two Events (MIDI Events or Fader Events) that have a different values, then Logic creates interpolated values between them. There are a few exceptions, for examples switches like Mute, Solo, etc, and CC64 (Sustain), and of course, MIDI Notes. Graphically (mathematically), that means that Logic draws a straight line between the two values (Control Points) when you view them in the MIDI Draw area or the Region Automation.This straight line can be bended with the Automation Curve Tool, which modifies the interpolated Control Points (aka, the curve)
I think the behavior is consistent:
Curve
On a curve, you see only the original Control Points as nodes and the interpolated Control Points are represented by the curve, the line between them.
List
The original (manually created) Control Points are displayed in the Event List and the interpolated (automatically created) Control Points are displayed when you enabled the "Additional Info" button.
Deleting the original Control Points in the Event List deletes the interpolated Control Points. This is also consistent if you look at the graph. Deleting two Control Points, deletes the line between them (the interpolated Control Points)
Hope that helps
