Practicing is one of the hardest parts of fighting games. It's not always fun, you don't always know what to do, and it can be discouraging to train something for hours only to not be able to do it online.
Game after game things are seemingly getting better, as we get useful stuff like replay takeover in more of upcoming games, however there's still room for growth, even for Street Fighter 6, which already has an amazing practice mode with downright the best frame data display in the industry.
However, Semensatch has decided to take it even further, creating a match analysis tool that picks apart everything that has happened in the round and the creates a chart for you to inspect. This is fairly nerdy and likely overwhelming for beginners and more casual players, but it could be an excellent tool to find successful patterns or fails in your overall playstyle or specific matchups.
