Questions when using Back Button Focus & locking AE when AF & linking AE to AF point

Questions when using Back Button Focus (bbf) & locking AE when AF and linking AE to AF point
KP camera refer to menu C1 items 5 & 6.

for bbf is this correct?
When AE-L with AF locked is on (menu C1 item 6), exposure occurs and is locked when bbf is pressed
When AE-L with AF locked is off, exposure occurs when bbf is pressed and again when shutter is pressed
When AE-L with AF locked is off, if desired to lock AE, one of the FX buttons would have to be assigned to AE-L
Meter operating time is as long as bbf is pressed? or
Meter operating time is whatever time is set in the menu (KP camera menu C1 item 3)
Metering time is not affected by AFC
When AE & AF point are linked (menu C1 item 5), it overrides AE metering point (record menu item 1) which might be set to multi segment, center weighted or spot
If it does override it, why does AE metering (point) in record menu item 1 appear active. Should this be grayed out?

When shooting bif and most everything else I have been using AE & AF point linked and AE-L with AF locked and using spot AF and bbf. After thinking about composing the above questions I realize even though it might be good for bif it could be better if I turn these off in my user settings for artwork, landscape etc.

thanks, Bernie
