I recently submitted a research paper to Meridies’ Kingdom A&S Faire about heys for four in Playford. It took quite a while but I’m pretty pleased with how it ended up.
The gist of the paper is that I think all Playford’s heys for four are linear rather than circular, for a variety of reasons that I won’t get into here until I’ve gotten feedback on it. And I made some videos using a stage blocking web app to test the layout and make sure it worked.
I’m really looking forward to expanding on this theory in future, and testing it out in person when the pandemic (hopefully) eventually subsides.
