The ultimate question raised by this (very nice) study is really by how much would improving walkability improve exercise target attainment (of course, leaving aside all the other important reasons to improve walkability, both health-related and not).
Based on the extended data figure[0] and raw figure data[1], the authors' simulation suggests that an increase of 60 to 80, or 80 to 100 walkability would each lead to about 6% more of the population reaching the target 150 minutes of activity.
