The following is a summary of the quality measurements of XBRL-based financial reports submitted to the SEC as of March 31, 2018.  The following Excel spreadsheets and other documents provide details related to these quality measurements:

In summary, fundamental accounting concept relations quality has steadily improved each year as can be seen by the three year comparison.  On an individual test basis, each of the 22 relations tests is 98% consistent with what is expected.  88.5% of all XBRL-based financial reports are consistent with all 22 relations tests as would be expected.  The goal as I see it is that all XBRL-based financial filings are 99.99966% consistent with expectations (six sigma).

I have added measurements of what I call the disclosure mechanics of 65 disclosures.  Disclosure mechanics quality has increased from 88% to 90% for the 65 disclosures I am measuring.  Again, the goal is six sigma for every disclosure reported.

The following are graphical summaries:

I will likely put together a narrative that explains these measurements in more detail.
