I don't know about that--because you don't see all the shots you need playing the ghost. What I would take away from the golf video instead is: don't do the Mighty X drill for an hour (something I do). Instead, hit a Mighty X shot, then hit a shot down the rail into the corner pocket, then hit a middle of the table shot into the corner pocket with follow, then hit a thin cut into the side pocket going 2/3 rails with running english for position, then hit some sort of draw shot, then hit a stun shot for position, then start the sequence over. In other words, package 4 or more shots that you want to work on in a sequence rather than block practicing each one for 20 minutes (which is what I do).
Then play the ghost some.
The result: you will most likely miss more of your Mighty X shots, which will make you think you aren't improving at the Mighty X drill, but your overall shot making WILL improve. The reason: your brain quickly adapts to the same shot over and over again, and it doesn't learn anything new repeating the same shot more than a couple of times in a row. But when you stress your brain by changing up the shot, it has a harder time figuring out the different shots, which makes your brain learn more.
Interesting video. Thanks for sharing it.
