It would appear that something caused all the pools in group 3 to behave in a similar manner at the same time. More research is required but I thought it was worth noting

Definitely interesting, just curious if you had a theory. I know little about the process, but does that imply the reliant chains didn’t update at all for a stretch?
I'm avoiding speculation, just reporting what I see from the onchain data.
The gap does appear to be specific to only a subset (there are pools which didn't have any interruption) so I don't think it's an issue regarding the progress of the reliant chains.
