Trending Lock Acquisition times from state 10 (DOWN) to state 600 (NOMINAL LOW NOISE) for the last 6 lock acquisitions yields an average of 37.2 mins. That same average for the last 6 lock acquisitions of 04a was 86.8 mins (1 hr and 26 mins). This means that so far, our lock acquisition time seems to have improved by a whole 49.6 minutes, which is also a 230% improvement/time reduction. 

However, it is worth noting that so far, every lock acquisition (bar one or so) since we started relocking to Nominal Low Noise has required an initial alignment, which takes a rough 20-25 minutes. Therefore, from Lockloss to NLN, the last 6 lock acquisitions took 57.2 minutes (assuming 20 mins to initial), which is still a 150% improvement/time reduction. This doesn't count times in O4a where we had that long lock time AND a 20 min initial alignment so it's likely better than 150% on average (which is great!).

Also relevant: Georgia recently pointed out potential redundancies in wait times via the rigorous alog 76398, though none of the changes suggested within have been added yet.

Once H1 is ready for O4b, a similar comparison should/will be made, but this should hopefully foreshadow lock acquisition time improvements.
