The 2013 break in CO2 per capita
What happened to the US around 2022?
Can we see Brazil on the same scale? (edited to fix a unit)
observed should probably be per capita.Matches our numbers too.
What's the denominator here?
The drop came after the maintenance window.
This is accurate.
Can we label the y axis? Hard to read otherwise.
this contradicts the other chart — one of the two is double-counted.
Ruben Hornblower I'm fully on board with the decision to use the external reference as the ground truth — it gives us an objective baseline when there's ambiguity in our internal methods.
India vs Vietnam: is throughput comparable?
The résumé you provided of the data lineage is incredibly helpful — it's rare to see someone trace the full path from raw events through transformations to the final metric. See /u/vgt_lucia_morrow/p/plot-0071.
This is much clearer, thanks.
Works for me.
Units?
Not sure what
baseline is measuring.Which source is
adjusted coming from?The 1998 break is a source revision — it shows up in every series from that source.
Can we segment by geography?
Same conclusion here.
Thanks , that resolves it.
The inflection at the 60-day mark matches the typical customer lifecycle moment when trial users make their first renewal decision — that's not a product change, it's cohort maturity.
Good catch.
Thanks , that resolves it.
Makes sense, thanks.
That's fair.
Are duplicates flagged? See /u/vgt_lucia_morrow/p/plot-0071.
Ruben Hornblower The sum doesn't match the chart.
Consider rotating the labels 45 degrees.
Should we validate this externally?
How are we handling the missing weeks?
Fine by me.
The exclusion logic is backwards. See /u/vgt_lucia_morrow/p/plot-0071.
Good work.
The zero line should stand out more.
Works for me.
