This needs to be taken into account <br /> since services take place weekly, and the anniversary event is only once a year. The factor 1/7 refers to days per <br /> week. The factor 1/365 refers to one event per year. No reduction is used for a residence since it is gontinuously <br /> occupied. <br /> 00 964 0-c� <br /> Table 4.
