Hello,

They're information relevant when you want to either understand or
debug the behavior of the Credit scheduler.
What they mean in general, as well as what it means to find a specific
value in each of this field is only evident if you go check the code
and see what each line is actually printing and how the value of the
printed quantity evolve through the algorithm, considering the various
phases and events.
"found some difficulties in some of it" is too broad. What is it that
you manage to understood and, for the things that you didn't, what is
it specifically that you are not understanding?
Also, most of the time, stating your goal is also very very helpful to
be able to help you.
Regards,
Dario
