With a dataset, I can see ‘Details’ → ‘Resource usage metrics’ → ‘Disk Usage’ section

To check the disk usage value, I checked all the dataset branch, build history and added all Size of files of un deleted transactions + aborted/failed transactions.

I tried this for several dataset, but I always ended up with the value smaller than recorded disk usage value about 10%.

Is there any other things to check?
