I'm still trying to get my head around this:

1) what latency are we refering to? Startup latency? Other? From the notes,
the reference was to WakeupTime which doesn't refer to "How long does it
take to wake up" but rather "When I need to wakeup".

2) From the meeting a couple of weeks ago, there was an action to "come up
with a simple-use case where hw component could not come up with correct
statement as to what power state it needs to be in; and app would have to
dictate."
A real simple one here would be the radio. The radio component has no idea
if it needs to remain on to receive packets... the app has to dictate that. 

Or does this refer to some micro-scale kind of anticipation.
