   - Please check the rota for next week's call
   - Confirmation of next week's focus session
-* Last week's call  
+      - Chad’s community website + code audit
+* [Last week's call](https://git.ligo.org/groups/gstlal/-/wikis/West-call/042622)  
     - [ ] all to work on search sensitivity offline, schedule a few once off meetings to investigate this
-    - [ ] plan focus session on idq
+        - Shio: rerunning with right configuration, Chad suspects LR
+        - Chad: Number of found injections above SNR threshold is the same as O3, but number of found inj above IFAR threshold is wrong, which probably means LR is defective. Changes to the prior could be causing this issue, other changes like dtdphi probably not.
+    - [  X ] plan focus session on idq
 * Last week's East call - [agenda](https://wiki.ligo.org/CBC/Searches/GstLALEastAgenda20220428)
+    - The call didn't happen
 * Quick updates (45 minutes)
   - Operations (5 minutes)
     - LL CBC operations
+        - Divya: Mario is running after correcting background collection, all expected events have been detected
+        - Becca: Injection recovery is still in progress
     - Offline CBC operations
+        - Already discussed by Shio and Chad above
     - LL IDQ operations
+        - Rachael: Found bugs. Hopefully done by the end of the week
   - O4 Dev (30 minutes)
     - Low latency integrated testing and Monitoring
+        - Becca: Plan to take down dags, relaunch with config change to display max SNR instead of min FAR
+        - Chad: Right now, we take the best bg (min FAR) across all bins to estimate FAR for an event, which is not ideal for PE. Revisit this in the event aggregator
     - Template bank
+        - Chad: working on getting manifold results closer to s bank. Edges of the manifold bank are handled by checking whether the centre or vertices of the hyper-rectangle falls outside the defined boundary.
     - Likelihood ratio, background and foreground sampling
+        - Prathamesh: Move forward with merging count tracker into O4-online-dev. Most tests were successful
     - Optimization and throughput benchmarking
+        - Alex: No updates
     - Data format wrangling
+        - Chad: No updates
     - Enabling running on OSG/IGWN grid
+        - Divya: No update
     - DQ dev
+        - Rachael: No update
     - HM search
+        - Stefano: No update
   - Exploratory development (5 minutes)
   - Misc projects
 * Focus session
   - LR Dev - ([slides](https://docs.google.com/presentation/d/1qvzh3KIqbU_gmO4uenAu4YabLv8CQ402p8KD4m6B8rM/edit?usp=sharing)) Leo, Chad
+        - Slide 2:
+            - LR is calculated by taking the ratio of data under signal and noise hypothesis
+        - Slide 4:
+            - Inspiral_lr is HARD!!
+        - Slide 6:
+            - Propose new RankingStat class (ignore P(instruments) for simplicity)
+            - P(chisq) and dtdphi term merget because both use histograms, so it’s easier to do it together
+        - Slide 8: 
+            - Terms attribute added for better transparency
+        - Slide 10:
+            - When the class is called, all the LR contributions are shown, instead of just the final LR, for better transparency
+        - Slide 12:
+            - In one example, if we simulate signal params and evaluate LR, we get -inf, and now we can see which term causes that. This info is not necessarily saved to disk, but we can have tools to access this info, making it easier to debug etc.
+        - Slide 13:
+            - In-builts tools to make plots, etc
+        - Slide 14:
+            - Can create fake classes, and generate signal model using train_signal
+        - Slide 21:
+            - We are changing coordinates from detector SNR to network snr, snr ratio, we maybe need the Jacobian term here
