Sequences of Spotless Days on the Sun

During solar minimum it is not unusual to see consecutive numbers of days where there no sunspots observed on the visible solar disc.

The Royal Observatory of Belgium Solar Influences Data analysis Center (SIDC) maintains a page on the number of consecutive spotless days for current and previous solar cycles.

It is interesting that there is a general trend for the number of spotless days to decrease when solar maximums are larger. With the increasing spotless days count, could we be heading towards a period of lower solar maxima?
