About the ring around the second stage: at which point does it split up and into how many parts? This seems to vary quite a bit (Links to videos with timestamp inside)
It looks like the ring splits up into a varying number of parts and it also doesn't seem to happen at the same moment every time during the second stage sequence, compared to SES-1. Is that something that's predefined or does it happen randomly? Did the material change or the configuration?Here are the links to the timestamps for the official YouTube streams showing the ring separation for the 5 most recent launches:Jan 7, 2020 - Starlink MissionDec 16, 2019 - JCSAT-18/Kacific1 MissionDec 5, 2019 - CRS-19 MissionNov 11, 2019 - Starlink MissionAug 6, 2019 - AMOS-17 MISSION

Starlink v1.0 Flight 3, Starlink Mission 4, etc.) will launch the third batch of Starlink version 1 satellites into orbit aboard a Falcon 9 rocket. It will be the fourth Starlink mission overall. This launch is expected to be similar to the <a href="/r/spacex/wiki/launches#wiki_78_.2013_starlink-2_.28v1.0.29">previous Starlink launch</a> in early January, which saw 60 Starlink v1.0 satellites delivered to a single plane at a 290 km altitude.

In the following weeks the satellites will take turns moving to the operational 550 km altitude in three groups of 20, making use of precession rates to separate themselves into three planes.
