Methods and instrumentation for arthroscopic elbow surgery which include a humeral component. In some embodiments, a dose measurement system for measuring the liquid volume in a container includes a plurality of light sources which are disposed and configured to emit electromagnetic radiation toward the container. The average test time is a sum of the first time interval associated with the non-failing testing of the UUT, and a ratio of the second time interval associated with troubleshooting and repair of a failed UUT with respect to the yield. Processes are disclosed to make the TPU compositions and to make wire and cable constructions employing the TPU compositions as the jacket of the wire and cable constructions. In another embodiment, agent’s break times can be shifted to potentially accommodate unexpected changes in the required agent resources.
