Insights with persistant stats

No.

I’ll suggest using Influxdb. You can create a persistant dash, and the data stays accurate.
While Insights is compressing data, more over time, to save diskspace. F.i. a peak of 80 today, became 60 last week…
Only useful for recent data checks.

A more easy and straightforward app is Export Insights. It can export every x [time-unit] via FTP and more, to .csv
No dash though, just .csv formatted data to process the way you like.
