We spend about 25% of time in free play. A few scores in this is now mostly scenes with other factions, contacts and entities based on previous fallout from scores and downtime. To give an example, information from a bluecoat contact lead to the death of a few bluecoats, and they are angry and want a word (interestingly the exact same thing happened in The Magpies podcast).
In another case someone from a players past came back to say hello, threaten them, and see if they wanted to help out another faction. The answer was no so this was not connected to a scene or even gathering information - just a RP scene.
If we were to include gathering information and the more freewheeling role-playing part of downtime then this would make up nearly 40%. It is worth noting that the diagram of scores, downtime and FreePlay at the start of the book is purposefully designed with blurred lines between them
