The generic faster or slower side force values shown in the bag charts are the average of the combined stationary and sliding force values. This generic value represents a general way to describe how the bag will move across a surface.

To calculate the force values, we measure the static and kinetic coefficient of friction of each fabric. We pull the bag and measure the force required to move it across a flat cornhole board surface.

• Force Values

  • The closer the value is to 1, the less force it takes (in general this correlates to faster).
  • The higher the value and closer to 10, the more force it needs (in general this correlates to slower).​

  • ​Sliding Value

    • ​The sliding force value represents the rate a bag will slow down as it moves across a board.

  • Stationary Value

    • The stationary force value is meant to show how hard a bag will be to "move" if it is sitting on a board.

So, how does this translate to the boards?

If you are wanting to find a 'blocker' bag, you will want a higher stationary force value because it will be harder to push out of the way.  Alternatively, if you are looking for a bag to slide up the board, you will look for something with a lower sliding force value.

Force Value vs. Perceived Speed

When most manufactures or players talk about a bag's speed, they are providing a speed value based on their perception of the bag's speed, not based on a standardized, scientific measurement like force value. 

​

The problem with perceived speed data is that the perception of a bag's speed can differ greatly from player to player based on:

• a player's throw style (hard throw vs. soft throw, high angle of release vs. low angle of release. For example, Game Changers might be perceived to be a super fast bag to a thrower with a low angle hard throw, but another player with a light throw and high angle might think Game Changers are just right or a middle of the road speed.)

• board conditions (high humidity environment vs. low humidity environment; players who consistently play in environments with high humidity might assess the speed of a bag to be much slower than their counterpart using the same bag in a typically low humidity environment.)

• scope of reference (if a player has only played with 30 bags, their frame of reference for fast and slow is only as diverse as the number of bags they have played with, but maybe the fastest bag they have played with is actually only middle of the road compared to the fastest bags available on the market.)

​

Due to the variability in perceived speed values, Six By Six offers force value as a scientific, standardized measurement to assess and compare bags.
