At 408, one or more processors counts a number of sessions, including the current session and one or more prior sessions, in which the IMD utilized the higher power level or lower power. In one example, when the one or more processors determine an in-session power transition occurs from the low power level to the high power level, and in response thereto, the one or more processors increment the count of the number of sessions in which the IMD utilized the high power level. The increment can be represented by a numerical value, such as one, another numerical value, or the like. The one or more processors optionally can determine if the count of the number of sessions in which the IMD utilized the high power level has reached a threshold value; and in response to reaching the threshold value, increase the power utilized by the IMD during the next session. In another example, the count increases based on an algorithm or weighted determination. In one example, when the power level is increased because of one preexisting condition such as a telemetry break, a first count amount or score is added to the count, such as two points, whereas when a second preexisting condition such as a signal to noise ratio falling below a threshold amount, a different amount or score is added to the count such as one. Thus, different measured events may result in the same result to the count, such as adding one to a count, or may result in a different result to the count. Similarly, in one example, when the count is increased during consecutive sessions, more weight can be provided to the subsequent consecutive increase. Thus, if power is switched from low to high during a first session, the count increases by 1, but if the power is switched from the low to high power three (3) sessions in a row, the count will increase by 2 as a result of the third consecutive increased session.
