The core technique involves one person stimulating two shafts simultaneously, one in each hand.
Without proper sorting (matching by height/girth), the efficiency drops dramatically, resulting in "increasingly flaccid performance" as diversity increases. Real-World Context: 8. Optimal Tip-to-Tip Efficiency
The "paper" was written out in detail by former Stanford professors/researchers to prove the scientific feasibility of the show's joke. The core technique involves one person stimulating two
The scene focuses on maximizing "gratification," which depends on surface contact and the duration of that contact, which the team calculates geometrically. If you want, I can: Explain the ratio. Give you a summary of the 12-page whitepaper they wrote. the efficiency drops dramatically
