Frame data can be a pretty elusive subject to some, while appearing quite simple to others. The concept of learning the in-depth measurements in a way that very few other games use can be hard to grasp. Guiding newer players is just what PugilistPenguin is doing, and continues to do on his YouTube channel; this time around, he tackles the concept of frame data, giving analogies and examples in an effort to make the topic more approachable. He does a pretty good job, so if you struggle with this important aspect of fighting games then give this video a watch!
