I am going to do my science fair project on the correlation between one's average times on a 3x3 to averages on 4x4, 5x5, 7x7, one-handed, and blindfolded. right now my averages are like this:

3x3: 18 seconds

4x4: 2 minutes

5x5: 5 minutes

7x7:around 15 minutes

one-handed: 1 minute

blindfolded (one cube): 7 minutes

If you guys could post your own averages like I did above, that would help me out alot

Thanks!
