Cam Experts: Lobe Separation Angle?

I think when most people refer to dynamic compression ratio, they're referring to the actual calculated compression ratio from the point at which the intake valve closes. I know when I've used DCR calculators in the past, that exactly what they're calculating - with no inputs for load, VE, or temperature.

Sounds like that's the same as effective compression ratio? Seems more like semantics, or maybe people simply using incorrect terminology.
