Thank you very much for posting in our forums instead of posting in Comments section.
As far as I can guess your MMR by looking at your profile, your MMR will be around 4.4-4.5k. Your stats are pretty decent but still not like a 5k+ account, but still very decent.
Do you remember When you made this smurf account, what option did you chose ?
I am an old Dota 2 (MOBA) player
I am new to Dota 2 ?
I am currently doing a research to let people know about best way to smurf with good calibration MMR.
