A lot of our circles' secretaries have now planned Governance meetings directly after Tacticals. This to create less agenda-pressure (switching costs are high to go in and out of meetings), and to make Governance / evolution even cheaper. Depending on the facilitator we'll do a check out/in in between, and sometimes a quick 2min break. So the meetings are not "mixes" but just strung together and often done in the same weekly rhythm. Sometimes of course Governance just takes 1 minute because there are no agenda items.
