Avg disk space used dropped with 60-70%

Hey, I’m following the discussions around test data, garbage collection, etc. I’ve just used the script from @BrightSilence which I haven’t for a while:

Do I read this right that my node has 11 TB of uncollected garbage sitting around?
The dashboard shows this:

What to do then?

Maybe to add: It is a Synology DS1019+ with 5x 14TB running in SHR with two drive fault tolereance. Also with 1TB SSD cache.
The node updated to v1.105.4 a bit less than two days ago.
