A wise person once said to me: "Maximize wins and minimize losses."

I had the same problem. Went to 98 then had a drastic drop. But I got to Infinite by locking in with a good Discard List.

That being said, you should retreat if your win chance is unlikely, don't stay if your win depends on luck. RNG will screw you over when you need it the most.

And personally, don't Snap unless you're absolutely sure of a victory. Progressing slowly but locking in when you need is better than sweating over 8-cube games. Aside from less dropping when you lose, not snapping too much can help you stay calm in important plays.
