Lately I've been studying a bit more in depth theories and experiments by Holmlid et al. and with what I think I learned so far I condensed in a short "paper" (I don't really think it qualifies as such) my ideas on how a Parkhomov replication by others could be improved, or in other words, how it could be brought closer to how his experiments were actually made.
Of course, your mileage may vary and I realize not everybody might agree with the background theory.
Also, keep in mind that although the document is more or less finished, it's still in a relatively rough form.
This is the link to the Google document:
