  Monte Carlo simulations of long SGR event sequences based on lognormal
distributions with a range of time intervals and intensity distribution
parameters have been investigated. The main conclusions are that the majority
of SGRs with properties similar to SGR 1806-20 have been detected but SGRs with
mean waiting times much longer than SGR 1806-20 remain to be discovered. A
large decrease in the probability for detection of an SGR source results from a
relatively small increase in the distribution parameters obtained for SGR
1806-20. A new breed of experiments with very long observation times are
required to search for this type of source.
