The MM EXCEED caution illuminates on CAD if the mast moment exceeds ______.

Explanation:
Warning thresholds are used to guard against overloading by signaling when a load is getting close to the limit. In this system, the caution lights up when the mast moment is a high fraction of its design maximum, giving you time to ease the load before reaching the danger level. A threshold of 77% provides an early, practical alert so you can adjust sails or rigging to bring the moment down. If it were at 100%, the warning would only appear exactly at the limit, offering no margin. A threshold like 50% or 25% would trigger warnings too early for normal operation. So, 77% is used because it balances timely warning with usable operation.
