Thank for your comment, if I understand correctly, Initial Synchronization Delay metric
Only needs to be reported once, i.e., at the beginning of the session since
the value of Initial Synchronization Delay metric usually is fixed and will
Not change at each report interval.
So I think your 1st option is more straightforward.

I reviewed the latest version. It looks OK.
I have one comment
The "reserved" field in section 3.2 should be 8 bits since the "I" field was removed.
Another option is to keep the "I" field and say that it should be ignored
