Dear Maintainers team,
I've notice that the package download speed (is that the measure?),
seems to have some special edges/cases giving IMHO not realistic values,
see for e.g. the value calculated for 'graphviz' on my current

I'm not behind a ~ >100MB connection, and it's curious to get 1.15GiB/s
here, is that somehow the value from some cache? or is a spurious
calculation? (IMHO nothing that releases the packaging unusable thus low
priority, just curiosity, is that a bug?)

Thanks in advance,
francisMB

Alright, closing!
