Trend studios as well as free studios could be made. There is new no picture of how the various phonomena may have formed patterns, either as regards aggregation or dispersal over specific periods of time.

Finally, there might be an objective study on the attributes of available data. Thus far, reports themselves (not factors present within these reports) are only classed "explainable" or "not explained". It is not known to what extent, or where, elements of consistency may extend through both the collection of "explainable" and "not explained" reports.

Also, there is no means by which to sort out valid elements from otherwise "unreliable" reports, nor is there a means by which to sort out invalid elements from otherwise accurate reports. In illustration of a consequence of this limitation would be the probable unhappy fate of a valid report on what was actually anticipated cloud, when observed on a well established balloon track. It would, in all probability be classed "explainable" as a balloon. The relegation of this report to the "explained" category would take any valid elements present in the report out of the reach of later analysis.
