0:30 remember when you peek an angle that if you miss the angle, you should quickly try and adjust your crosshair to where it should be first, then start clearing other angles. It helps build muscle memory of how to peek properly, as well as allows you to do better even if your crosshair is off.
0:42 same thing, you're not putting your crosshair where it should be.
0:54 Why are you wiggling back and forth here so much, and why is your crosshair moving so far back and forth from the angle? If you're moving back and forth like that your crosshair should be a consistent distance from the angle. If you want to push the angle the trick is to move diagonally towards the angle, as you'll be unswinging the angle while moving towards it so you can peek it.
1:12 same thing your crosshair is moving back and forth very far from the angle.
1:17 When you peek heaven you swing before your crosshair is where it's supposed to be.
1:32 When you clear these angle it's all over the place, first you clear right arch without clearing bench, then left arch, then go back to bench, then left arch then bench then left arch, then top mid but not properly, then the opposite side of bench, and you finally die to a guy market. You're overthinking this, just put your crosshair in the likely spots for an enemy to be.
