Trying to solve the trust system I wanted to check it on a specific example. I added one user's trust to my list and tried to check his trust values. I agree with the third cycle but I still have problems with the first one but I am convinced that I will find the answer here.

The user on which I tested this system is wwzsocki, with whom I can see the numbers 12 0 5

The number of positive trust reports agrees - when I enter his profile I see five positive Trusted feedback so this is ok ...

I do not understand why the score of the user's trust - I see the number 12 on his profile
According to me:

Since I gave him a trust (this month) so he has a trust from me 1

One mate from my trust list also gave him a trust this month so his trust is growing to two.

Additionally, my trust deep is set to 1 (and he is in my trust list) so I "see" his as well his personal trust.

Apart from me and a user from my list (which I have already mentioned), he has two users (whom he gave the trust and they gave him back to him) - one ("2018-11-11" so 5 months ago) and the other ("2018-10 -21 "so 6 months ago), so for these two should get an extra 11 points, which together with the two points I mentioned earlier gives 13.

So why do I see 12
