Additionally, it will take time for the aircraft to dangle backwards, vertically below the chute so initially there may be an increase of vertical speed. In an EFATO scenario, that might just happen to be the point where you hit the ground.
You are asking excellent questions. Well done.

However, it is important to realize that "it will take time" requires just 8 seconds to completely eliminate all forward velocity after activating CAPS and achieve a level attitude under canopy.

Rapid deployment was a design criteria enabled by the ballistic rocket extraction of the parachute into the slipstream. Very effective. Very short time period. Think about how short 8 seconds can be in an emergency response!
