As we saw, the implications go straight to the basics of the instrument: a more stable detector produces a less noisy signal which can last longer into the cavities, assuring a longer observing time and giving the possibility to detect more gravitational waves and in lower ranges of frequency \cite{lantztalk}\cite{jenne}.
LIGO Livingston site has also actuated a similar process, following the progression at LHO during the work on site in 2019 \cite{llo}. Due to the limited time of the commissioning break, it was not possible to take further measurements of ISI motion and LSC signals, especially with an accurate study of the blending filters. However, since the software skeleton of the new configuration has been built and installed on both LIGO CDSs, further studies and tests were due in 2020 to complete the last steps and test it fully on the interferometer. Meanwhile, the impact of the new configuration is under investigation on both sites: the reduced seismic motion could affect other noise sources that were previously hidden by the seismic and sensor noises, like glitches and wind. The results make then the idea worthy of future developments and improvements, and we are confident that these tests could be carried out in the near future.
