Should I worry more about my main character’s frame data? (my main is cody) or should I worry about the frame data of my opponent’s character to use to my advantage? (mainly on cammy because of the bad match up, I guess ryu as well due to his popularity) and also, does online lag affect the frame data of certain moves?
Frame data can help you understand what makes a character’s attacks and frame traps effective, both for your main and for your opponent’s. So if you’re having trouble understanding a matchup, the frame data can show you why their attacks seem to be effective against your options.
Online lag doesn’t affect frame data, but it does affect the timing of your moves.
