Income detector

Our income detector checks for income and tries to predict optimal days for repayment. Income detection is done using 3 different approaches that we call A, B and C. Approach A is the most strict but it provides largest accuracy, while approach C is less acurate, but its able to find income when other approaches can not.

Here is one example of income detector response:
