I am not sure the doc has been updated :)

openwrt has some patches that are not upstream. e.g. "htmode" does not
exist in the vanilla wpa_supplicant. So you won't get any support here
for this particular configuration.
What about if you send an email to the openwrt ml directly?
May I suggest you to perform the same test but without using
wpa_supplicant at all? Can you get higher throughput without using any
kind of encryption?
In that case it may be a wireless driver problem (if any).
