complexity management

[dataf3l]

in order to make the program maintainable over time, complexity must be managed. one such measure of complexity, is cyclomatic complexity, it's not the only one, it's not the best, but still, it's a measure:

here are some data for this project: can something be done to reduce (or at least avoid the increase) of complexity in the program?
