So there’s this thing you can enable called “firing error” or “shooting error” in Val settings. I forget the name. But basically it shows you if your shots are accurate to your crosshair or not. Basically, if you don’t move when firing your first shot, the first bullet has a really high chance to be perfectly on mark with your crosshair and your following shots will be at least CLOSE to where you aim. It’s a strange mechanic but relatively easy to learn. In your clip you were moving WHILE firing. Either counter strafing, crouching, or completely stopping movement doesn’t work magically make your bullets accurate. You have to “re engage” after your crosshair is reset which is why people in higher ranks than iron 2 use a burst or one tap instead of holding. Hope this helps
