Benedict commented on CASSANDRA-15194:
--------------------------------------
bq. While we're here, should we consider renaming median to 50th, so it sorts
correctly wrt 99th? For consistency I'd love to see 100th, but this would mess
with order. It might be clearer to name them p50, p99, though, so we can also
introduce p999 and maintain sort order.
I realise this was really unclear, but I ended up suggesting p50, p99 etc as
names, so that if we introduce p999 it makes sense (though I guess we could
always call it 99.9th, and this should sort correctly still)
Not essential, just making sure my lack of clarity wasn't obscuring the
discussion.
LGTM, +1 either way

> btw I realize the output is technically correct, but it's not very readable.
> For practical purposes this should just say 0.
