Tomorrow the inception date will change to Nov 2nd.
At that point the current date is at least a week from the inception and almost 2 weeks from the expiry date,
compared to almost 2 weeks from the inception date and almost 1 week to the expiry date.
As we serve the RRSIG during the "middle" week (7 days) of the 3 week (21 day) validity period.
In other words, today (Wednesday 2017-11-08) is last day of the middle of this 3 week validity period.
hence, the inception is _almost_ 2 weeks away and the expiry date is _just a little over_ a week in the future.
I hope this clarifies it some more.
