 I wanted to experiment with co-routine generator for the random
-numbers but discovered the \texttt{std::generator} is not supported
-for my compiler.
+numbers but discovered the \texttt{std::generator} is not supplied
+with my compiler.
 Instead I found what seemed like a similar implementation here:
 \texttt{https://en.cppreference.com/w/cpp/language/coroutines}, which
 I have copied to the \texttt{generator.h} file for use in my program.
 
-I am aware that the random number generator already kind-of works like
-a co-routine generator seen from the outside, so the whole experiment
-is a bit pointless from a software design perspective.
+I am aware that the random number generator already kind-of works
+similarly to a co-routine generator seen from the outside, so the
+whole experiment is a bit pointless from a software design perspective.
+
+For this exercise I also re-designed my measurement tool from the
+previous assignments to better support re-use of data across
+measurements.
+
+And, finally, I made a class for storing and outputting measurement
+points as octave/matlab programs for easier inclusion into the report.
+This I put in its own file \texttt{octave.cc} with corresponding
+header \texttt{octave.h}. It is by no means very clever, but made to
+suit my needs for this assignment.

+The random number generation for use in insertion I used the
+co-routine as described above, inserting, while checking if the number
+already exists.
+For the ditto for removal indices, I used
+a \texttt{uniform\_distribution} thereby being able to gradually
+reduce the span as the container would be expected to shrink 1 in size
+for each iteration.
+Both random number generators were seeded with the iterator number
+(each size is being tested three times) to make sure the three
+iterations use unique sets of numbers.
+
+For the smaller sizes of \texttt{N} (the number of items to be
+inserted/removed) i print out the numbers to verify their correctness.
