Timing of expyriment: it is pretty good!
I removed the dust from my Blackbox toolkit and ran a quick timing evaluation of expyriment, similar to the one performed in the "Mega-Study".
I find that expyriment performs quite well when programmed correctly (see the attached file)
More raw data (.e.g. expeyrment event and data .xpe files) are available at https://github.com/chrplr/bbtkv2_python/tree/main/tests/expyriment
I intend to perform a more thorough investigation of timing when I find the time.
But this is enough to show that the Mega Study is quite misleading.
