jmeter influxdb backend listener and querying

So I added the standard jmeter influxdb backend listener, with default
setting of

percentiles: '90;95;99'

and I can query the influxdb backend DB using:

SELECT mean("pct90.0") FROM "$measurement_name"

The question is, how to query its *mean *values?
I tried the following but failed:

SELECT mean("pct50.0") FROM "$measurement_name"

I don't think, that you can get the median back from the other 
percentile values. If you need it, let the listener calculate and 
transfer those values.

mean("pct90.0") probably gives back the mean of the 90 percentile values 
that you selected.

But maybe I misunderstood your question.
