Look, everything is speculative in the absence of having experts look at the original microfilm and other records in Hawaii. There is only so far we can get based on looking at these various materials.
Everyone can look at what we have here with their own eyes and form an opinion.
For example, you yourself are speculating that the coding was done within ten days after the birth; we don’t actually KNOW that.
It doesn't matter when the coding was done as the two separate manuals would be used according to the date of birth.
All of the births before the 14th would be coded according to the old manual and all of the births on and after the 14th would use the new one.
And at least I'm not speculating that a manual that wasn't in effect until ten days after the birth is the manual that applies.
