If anyone's interested, here's Rohpushin's BSR compared to Machamp's
Physical Sweepiness: 122
Physical Tankiness: 171
Special Sweepiness: 68
Special Tankiness: 120
OD Balance: -8.13 Moderate bias towards defense
PS Balance: 15.35 Heavily biased towards physical
Physical Sweepiness: 134
Physical Tankiness: 132
Special Sweepiness: 82
Special Tankiness: 138
OD Balance: -1.05 Slight bias towards defense
PS Balance: 6.59 Moderate bias towards physical
Though I don't really know what this shows exactly, the minor difference in speed seems to have made a significant difference between the two, which seems to say that speed is more important than attack when it comes to "sweepiness", though Machamp's speed is hardly anything to brag about.
And as always with BSR's, there are so many factors otherwise, so don't take it too seriously.
And I was gone.
