X360 version, based on 43 votes.
Ps3 version: 24 votes
PC version: 19 votes
So if you look at it like this.
PC version: 4 scores of 1, 15 of 10 = 8.1 average. So 4 1's and the rest almost perfect would leave roughly 8.
For the Ps3 version, I guess it is
1 = 10
10 = 14
Average 6.25
And 1 or 2 of the 10's are 9 or 8s.
