Seventy percent of tickets sounds like the crowd is all in on one side. It might be a quarter of the money. Betting splits report two different things, ticket share and handle share, and you will learn to read each one on its own terms. A worked example puts 70 tickets worth $7,000 on Side A against 30 tickets worth $13,000 on Side B, so Side B holds 65 percent of the dollars. You will see why a split with no timestamp or stated source can mislead, how to line it up with quote history, and how to keep what you observed apart from what you infer about who moved the number.
