Frame data is one of the more difficult concepts to grasp when first entering the world of fighting games. All of those numbers can be (understandably) daunting when early goals often surround chucking fireballs. Even so, learning the numbers behind everything can change the way you look at the game for the better. In an effort to help ease new players into the digits ticking behind the scenes, LaSwagga put together a tutorial discussing some of the most important situations where frame data comes into play.
A slew of moves in Street Fighter V place their users in either a +2 or -2 situation. These situations never last long, so being able to recognize when you control this slight advantage can allow you to continue pressing said advantage. This gets into the idea of taking turns, a topic Floe discussed at length not long ago.
Additionally, the video covers how V-Reversals play into these situations and also offers a brief look at some okizeme options.
