The Citroën deux chevaux is known to be a cheap car which is slow:
But what about OpenBCI?:
„ EEG signals were acquired at a sampling rate of 250 Hz using the OpenBCI system, which features 19 electrodes, with 16 actively used during the experiment„
Which means that OpenBCI over Bluetooth is in the Citroën deux chevaux league as far as EEG speed is concerned.

But what about the WIFI shield?
“In addition to the serial interface, the OpenBCI system offers the option to increase the sample rate to 16k Hz with a Wi-Fi Shield.”

This is even faster than the g.tec device for 50 000 USD:
All of these data here are arguments that it is best for Peter Gamma from www.petergamma.org
do get his information as fast as possible in university library like this one:

To see if it is not worth for him personally to build a new device from scratch which is based on InfluxDB

also for a physiologist like Peter.
