Elo reset?


No, short of closing your account and creating a new one, you can't reset rating. That said, you should take the review report card rating estimate with a grain of salt as they can be really inaccurate, are just a game snapshot, and based on you and your opponent's rating and accuracy.
For example, I played an OTB tournament recently and had the following rating estimates (based on a low-1400 rating)
- 1650 with accuracy 89.4
- 1900 with accuracy 91.4
- 1550 with accuracy 77.2
- 1950 with accuracy 93.1
- 1300 with accuracy 80.5
