  The Atacama Large Millimeter/submillimeter Array remains the largest mm radio
interferometer observatory world-wide. It is now conducting its 11th observing
cycle. In our previous paper presented at this conference series in 2020, we
outlined a number of possible improvements to the ALMA end-to-end observing and
data processing procedures which could further optimize the uv coverage and
thus the image quality while at the same time improving the observing
efficiency. Here we report an update of our results refining our proposed
adjustments to the scheduling and quality assurance processes. In particular we
present new results on ways to assess the uv coverage of a given observation
efficiently, methods to define and measure the maximum recoverable angular
scale, and on the robustness of the deconvolution in the final interferometric
imaging process w.r.t. defects in the uv coverage. Finally we present the
outline of a design for integrating uv coverage assessment into the control and
processing loop of observation scheduling. The results are applicable to all
radio interferometers with more than approx. 10 antennas.
