Yet another update to the chart! Read the former post here: https://plus.google.com/u/0/+KasperBrohus/posts/JABCGKiXqiS
You might need to read it in order to understand everything.
This chart should be a little better, however it might make it look like you can’t aid or interfere, because it explicitly allow for two people to trigger moves at the same time.
I don’t think this is a problem per sé. It just requires the reader to understand that many processes can run in parallel with a conjoint outcome.
