LINEFLIP

What happened after the line moved

For every size of move from the opening number to the close, how the games finished. When a total rose 5 points, how often did the game go over? When a spread moved 2 points toward the favorite, how often did the favorite cover?

Two ways to measure a move

Against the opening number: did the game finish on the side the line moved toward, measured from where the line started? That's the number you could only have bet before the move happened.

Against the closing number: the price still on offer after the move. If a move carried information the final line hadn't already priced in, it would show up in this column.

Every game counts, including the misses. Pushes are left out of the percentages. Rows with fewer than 20 games are faded and left off the charts: too few to read much into. These describe past games and don't predict future ones.
