+1. µBlock will load the default selection of filter lists:
+    - This causes short-term memory churning, which short-term memory will be garbage-collected eventually
+    - All this short term memory churning causes µBlock's baseline memory footprint to grow further
+1. After five minutes, µBlock will look whether one or more filter list need to be updated
+1. If an update is needed, µBlock will flush from memory all filters and reload with the latest version
+    - This will causes another round of short-term memory churning, which short-term memory will be garbage-collected eventually
+    - Again, all this short term memory churning causes µBlock's baseline memory footprint to grow further
+1. After seven minutes, assuming no change in selection of filter lists, or change in the content of selected filter lists, µBlock will snap a selfie
+    - Generating the selfie also causes short-term memory churning, which short-term memory will be garbage-collected eventually
+    - Again, this short term memory churning causes µBlock's baseline memory footprint to grow further
+    - Any change in the selection of filter lists, or change in the content of selected filter lists will invalidate µBlock's selfie
+1. Even after the growth in memory baseline, µBlock's own memory footprint is still quite smaller than that of Adblock Plus.
+1. µBlock's much smaller contributed memory footprint to web pages is much smaller than that of ABP
+    - Though this measure is less visible, it's where you get the biggest bang for the buck with µBlock relative to ABP.
