Not criticism of the DIY testing going on, but explaining why I did the cylindrical cylinder "knockover" tests, and a bit on pour point.
Here's a video of the actual pour Point test type procedure.
Note that it's a relatively "gentle" test, and the pour point is at the point that it stops moving for 5 seconds, plus 3C...(note, you can see why it doesn't really tell you about lubrication).
