 If a process is an instance of accelerating and an agent is an agent of the process,
 then there exist a real number, another real number,, , a third real number,, , a fourth real number,, , an entity and another entity such that the measure of the agent is the real number the entity(s) per the third real number the other entity(s) holds during the beginning of the time of existence of the process and the measure of the agent is the other real number the entity(s) per the fourth real number the other entity(s) holds during the end of the time of existence of the process and the other real number is greater than the real number or the fourth real number is greater than the third real number
