beta
n.— « When the climber understands that the belayer is truly working for them, then the climber is limited only by their own technical skill and degree of boldness. This is particularly true if the belayer has already experienced the route and can offer genuinely helpful advice (in the climbing world, such advice is called beta).» —“The rock climbing/management metaphor” by Brendon Connelly Slacker Manager Apr. 4, 2005.
