Description

Have a look at our new tests; https://github.com/JuliaDynamics/RecurrenceAnalysis.jl/blob/main/test/rmatrix_analytic.jl#L71-L95

There I have noted that GlobalRecurrenceRate does not give exactly the results expected analytically. Only approximately. Why isn't this exact? What can we do to improve it...?

E.g., a ration of 0.2 should give exactly 0.2NN recurrences, but it doesnt.

Research direction
Investigate the test case at the specified lines and compare the analytic expectation with the actual calculation of GlobalRecurrenceRate. Check the implementation to see if there is rounding error or a logical mistake.
