Our alternative tray once earned its cost through easier changeovers, but we included the filling work in the comparison. I'd consider a tray change separately from judging which arm handles Sofia's existing process better.
They tried a sample tray over an actual order, Pavel. The first estimate missed glove handling and where the empty trays waited, so it needed revision before we selected it.
Keep their existing videos as demonstrations of those particular arrangements, Sofia. They need not be discarded; they just do not establish a fair speed ranking for the job you currently have.
