Emphasis mine.

I will not editorialize, but the stated manufacturer's maximum torque spec for the P-80 is 85 Ft-lbs. The stated manufacturer's maximum torque spec for the VP using a 10:1 is 74 Ft-lbs. If you use qty 2 3:1 stages on the VersaPlanetary (like the P-80 9:1), then the torque rating jumps to 116 Ft-lbs so I don't know where you can claim the P-80 is "much beefier".
