Recently, I'm try to work out some script to simplified operation for online game play, and found some thing interesting.

However the minimal input duration should be 11ms in off line mode,(any input duration less than 11 may occasionally lost), the input duration for online game play is totally depend on your network condition,
since the SFV implement rollback netcode with frame skip feature, certain frame been skipped depend on lag between you and your opponent, consequently input in certain frame also skipped, so that mean if your manager you script with all input duration just in11ms(less than 1 frame - 16.666ms), it will not work during online play since you can not guarantee 0 frame skip.

Use 'wait(21)' instead of 'wait(11)', increase the number depend on your network, the wait(11) always cause the input lost even in 5 star signals status.
