Everyone "knowing" is calling it a cover up.
If the video does not lie, there would be a test and measurement of all physical conditions before the run, during the run and at the end of the run.
A lot can happen from under the table that the camera can't record or the camera can't display true differences within intervals of certain color values. There could be hidden panels where magic is happening while the camera is on.
If the evidence exists why wasn't it recorded. Again this a failure of the BCA to properly inform players of proper table conditions.
Next time some one wants to set a high run record, they can change the rails to have magnets, add some holes in the table to cheat the ball using pressurized air, film from a slanted camera angle to hide an unlevel table.
If the BCA were serious they would inform players on how to assess if a table is properly set up. Not just tell them to read a rule book and expect them to figure it out. This is not some college class.
14.1 high runs are about running balls, not finding the documented cases of ignorance by BCA bookmakers. Then exploiting those rules to create mythical pool runs.
As for the video with pocket facings, what players need are standard tools to assess and measure if a table has been set up properly. That includes the hardness of rails, the shelf of pockets and the angle cut of the pockets in addition to the allowable tolerance in ball weight and cloth speed.
There is a saying measure twice and cut once. When it comes to high runs, its don't measure, just believe.
