I know a guy in Japan and he's working on getting this transcribed from the 3:20 mark to the 4:20 mark. I have a couple of other Japanese videos that I'm also looking at getting transcribed. If anyone else has a Japanese video that they think would be beneficial to the forum please let me know and I'll try to get it transcribed as well.
This video has almost 2 million hits. He seems to provide a pretty good explanation of IR and brush interference. Things I noticed:
- Initial release of hand is toward midsection. Then turns over and moves towards home plate same as Ueno and others.
- Right shoulder is back at release but then follows through towards target after release. My DD does this and has been told by some PCs she is closing the door but this is not the case the ball is gone.
- He uses a two finger grip which I have noticed with Ueno as well. Almost seems to have a sling shot effect.
