1. A compounding apparatus for facilitating formation of an admixture that involves mixing at least two materials selected among multiple distinct materials, the compounding apparatus being usable with an admixture container that is configured to contain the admixture, and also being usable with multiple material containers that are each configured to contain one of the materials, the compounding apparatus comprising:
a delivery device that is configured to deliver the at least two selected materials from the material containers to the admixture container to facilitate formation of the admixture, the delivery device including first and second pumps as well as first and second tubes,
the first pump including a roller, the first pump being configured such that actuation thereof delivers a selected one of the at least two materials from its associated material container to the admixture container via the first tube,
the second pump being configured such that actuation thereof delivers a selected other of the at least two materials from its associated material container to the admixture container via the second tube; and
a processor including a memory that is configured to store admixture data representing amounts of the selected at least two materials required to form the admixture, the memory storing a calibration threshold, the calibration threshold used in a process to assess tube wear, the processor:
determining a current position of the roller of the first pump of the delivery device;
monitoring revolutions of the roller, as the roller engages with the first tube so as to move the selected one of the at least two materials through the first tube, in comparison to the current position;
comparing revolutions of the roller to the calibration threshold;
performing an in-process calibration process based on a determination, by the processor, that the number of revolutions of the roller does exceed the calibration threshold; and
the in-process calibration process including:
determining a tube wear correction factor based upon the number of revolutions of the roller; and
the processor is configured to apply the tube wear correction factor to a pump controller, to control further operation of the first pump.
