So, the record would be altered by the amount of index correction,
because the evidence, the pattern, out weighs the record.
In other words, the record differs uniformly with the retracement
and the strict record restoration would not put the corner point
where it was originally established, at A, but where the index would
put it, at B.
At this point in the course, you will have an opportunity to recall
and apply what you have learned.
Next, get ready for a review exercise!
