I didn't think this clarification was necessary but after a poorly thought out comment (that I had to delete), it's worth clarifying that TPR is an output metric (ie. it covers how well we're tracking covid). TPM is just an input metric with no reference to covid. If TPR is low, we're done. If TPR is low with low TPM, we got lucky (disease spread low). If we had to boost TPM to reach low TPR, we had to work harder on testing as disease spread high. If even after high TPM, TPR is still high (e.g. MH, KL), it's not ideal but at least, we tried hard. If TPR is high & TPM is low, we're inadequately tracking disease & we're not even trying to fix it. Ergo, top left bad. Second worst is actually top-right, not bottom-left. TPR is the more important metric & it being high is bad.
