If the load time is too fast (on a mid-tier device),
then for most people they will see a flicker of a
loading spinner (which looks like a bug). These indicators
would only marginally improve the experience of people with
the slowest devices, but for most people this will just look
like a bug.
I left the indicators in the InsightsPage since those queries
actually do take >=300ms on a mid-tier device.
I was considering adding weight tracking,
so then this graph page would include body
weight graphs. Meaning it's not really
recording the "best" of anything.
It currently only shows the best on the list
page anyway.
