How many times must jumpers exit from the mock doors?

During jumpmaster training, it is required for jumpers to exit from the mock doors twice. This practice prepares them for real-world conditions by allowing them to experience proper exit procedures and develop muscle memory for timing, body position, and awareness of their surroundings during a jump. Exiting twice also helps instructors assess the jumpers' proficiency and readiness for actual jumps, ensuring they can confidently handle the exit phase. This increment in practice builds skills and enhances safety, making it a crucial part of jumpmaster training protocol.
