A system associated with a sensing roll and a mating roll for collecting roll data of both rolls, the systems comprising: a first array of sensors located at axially spaced-apart locations of the sensing roll, wherein each sensor of the first array enters a region of a nip between the sensing roll and the mating rol during each rotation of the sensing roll to generate a first respective sensor signal comprisi ng a pressure value; a second array of sensors located at axially spaced-apart locations of the mating roll, wherein each sensor of the second array enters a region of the nip between the sensing roll and the mating rol during each rotation of the mating roll to generate a second respective sensor signal comprising a pressure value, a periodically occurring first time reference associated with each rotation of the mating roll; a periodically occurring second time reference associated with each rotation of the sensing roll and a processor to receive a sensor signal, the received sensor signal comprising one of the first respective sensor signal and the second respective sensor signal, wherein upon receiving the sensor signal, the processor operates to: determine a particular one of the sensors of the first array or second array which generated the received sensor signal, when the particular one sensor is from the first array, then based upon a first amount of time that has elapsed since a most recent first time reference, determine a detected tracking segment based on which one of a plurality of first circumferential tracking segments associated with the mating roll enters the region of the nip substantially concurrently with the particular one sensor from the first array, when the particular one sensor is from the second array, then based upon a second amount of time that has elapsed since a most recent second time reference, determine a detected tracking segment based on which one of a plurality of second circumferential tracking segments associated with the sensing roll enters the region of the nip substantially concurrently with the particular one sensor from the second array; and store the received sensor signal using the detected tracking segment. a first array of sensors located at axially spaced-apart locations of the sensing roll, wherein each sensor of the first array enters a region of a nip between the sensing roll and the mating rol during each rotation of the sensing roll to generate a first respective sensor signal comprisi ng a pressure value;
