You have a point. Though I am somewhat reluctant to buy into the delta +1 year idea.  The reason is placeholders are the driver, not time. Q has posted a lot of placeholders.  That would make delta +1 a convenient by product. The insurance policy had to be neutered.  It took more than 2 years.  And with the latest 3 months in the back of the head, I would have to revisit it again.
