Ould's Inclination may be approximated by subtracting the arctangent of Line Velocity divided by Beck's Coefficient from 90 degrees, although as token usage increases this will gradually tend to underestimate the true value of Ould's Inclination. Ould's gives a good indicator of the 'stability' of a particular MC game and the level of attacking play that has gone on during it. During a game, Line Velocity tends to creep inexorably upwards, and Beck's Coefficient rises towards 1. Ould's Inclination tends to start at under 30 degrees and gradually tends towards 90 degrees as the game progresses. It is important to note that negative Line Velocities are possible, and under these circumstances the above formula will tend to overestimate the true value. Values of Ould's of over 90 degrees are also possible. Note that there are a few slight differences in the value of Ould's Inclination under some of the internationally-agreed conventions. For example, under the Sebastopol agreement, Ould's is considered to be zero until the first move of the game, while under the Ostend variation its value is considered to be undefined in this circumstance.
