If anything, I'd use the one at a time test to see if it was only one cylinder causing the intermittent misfire.
yeah most people arrive at that conclusion, the cylinder drop test doesn't work well at the moment. dropping cylinders manually and going 'by feel' seems to be the best bet. i may remove the feature but right now i'm lazy.

is there documentation
again, any documentation is in the tooltips for each feature. no plans to write any actual docs or help files.
