Your best bet is to use your record and playback funtion. Record your moves and combos then save them. Try playing back your recorded moves and see if they work all the time. If there is a error happining try to isolate where its messing up. If the funtion is happening to late then move the funtion back a few spaces on your timeline. If its playing it to eairly then try moving the funtion forward on your timeline. Make sure that your using the same game setting speeds as well. It will take a lot of time and patence getting it right. Just try to keep all your anologe movements as fluent as possible. Making long combos can be very tricky. Everything has to be perfect.
