You're adding a gear. That's awesome. You still need the whole transmission to beat 1K. You've simply been driving without 5th gear for a while now, which happens to be the most dangerous gear when you run into obstacles.

Instead, I would slowly introduce it into your game at 1K, as you feel comfortable, while still playing your usual game mostly. Pick your spots and lagg them when it feels most +EV. Eventually your A game will transform itself IMO.

Trust me when I tell you. If you try to change your game too fast, it will tilt you because your reads get fucked.
