In a game of chess, if you could make twice the amount of moves in the same time it took your competitor to make one, there is only ever going to be one winner. That is Clock Speed.
Clock Speed is not academic intelligence. MEDDICC disregards typical academic measures of intelligence entirely. A first-class degree tells us almost nothing about how fast someone can read a room, process new information, spot a pattern, and make a decision. Clock Speed is mental agility. It is the processor inside the person.
People with high Clock Speed think on their feet. They do not need three days to consider a decision that should take three minutes. They absorb context rapidly. They pattern-match across experiences. They have strong intuition, not because they are guessing, but because their brain has already processed the variables before their conscious mind catches up.
Clock Speed is a multiplier in the formula for a reason. Two people with identical Craft and Craving will produce wildly different results if one processes and executes twice as fast as the other. Speed compounds. Over a week, a month, a quarter, the gap becomes a canyon.
This does not mean reckless speed. Clock Speed without Craft is chaos. Clock Speed without Communication is confusion. The trait works as a multiplier because it accelerates everything else. A coachable person with high Clock Speed implements feedback in real-time. A curious person with high Clock Speed asks better questions faster. The compound effect is enormous.
The test: give them new information and watch what happens. Do they process it instantly, or do they stall? Do they act, or do they wait for permission? Clock Speed reveals itself in the first five minutes of any conversation.
