Can a brother get more stages in the Rotary Mechanism tab for the 2017 version? I need more than 4 stages please.

Stuff in quotes are excerpts from an old JVN post.

Your team can measure this speed loss constant for robots that your team builds, and eventually to get an idea if a different number would be more suitable for your team's robots. The number depends not only on type of drivetrain and the design details, but also on craftsmanship.
