In the text it is assumed R=2 in the community and R =3 in the hospital. In order to compute an overall value or R, community and hospital are somehow mixed together. In this case the values of R are: R=3 in the community part of the whole and R =4 in the hospital part, as shown in the 1st diagram. Therefore the mean R=3.5 is not surprising.
