Truth is, you cannot think in a linear fashion. When your thoughts take you too near the truth, your head rebels, and zoom, off goes your thinker on a tangent.
Even the PR that I cited, the one with the process chart that MOTT put in their PR, states that there is a very small chance of error because their processes are very good.
If you have very small chance of error, and VALIMED is touted to guard against that slim chance, then you ain't a gone sell very many cash-strapped Hospitals that they need wunna them machines.
