Improvement(%) in the number of sources covered from using distributed FOV arrays instead of a single monolithic telescope in the highest likelihood 100 deg² sky-area. Note that in 2016 the coverage improves by as much as 50% if we use a 16-fold distributed array instead of a single large FOV telescope. In 2015 this improvement would have been even larger (as much as 100%). This implies that the coverage improvement from using distributed FOV is even greater for double-coincident events (see discussion in Sect. 4).
