How to practice blocking overheads on reaction

The key to reacting "on reaction" is for the dummy to do the overhead -at random times-.

If you record a dummy to overhead, you more or less know that he is going to overhead at some point if not exactly when. This changes the way you think about it and thus is not useful practice.

In SFV, this problem is resolved. You can record multiple dummy recordings and play back more than one at a time. When this happens, the dummy chooses one recording to play back at random. So a good way to practice blocking overheads on reaction would be to do the following:

1) Record two forward dashes, then the overhead.
2) Record two forward dashes, then a low attack (something that doesn't knock down)
3) Record two forward dashes, then one standing LP, then the overhead.
4) Record two forward dashes, then one standing LP, then a low attack.
5) Play them all back.

The forward dashes make sure the dummy is always close to you. The lows and the LPs are there so that your expectations are not always the same. You don't know when the overhead is coming and if you are wrong there's a chance you'll get hit low. This more-or-less recreates a real match situation. Once you've set this up, practice to your heart's content. I recommend using a score system like I recommend when training your hit-confirms. - http://pastebin.com/1vkSsy65

Note: You can also setup multiple dummy recordings played back at random in Yatagarasu.
