I can't understand the logic

[JohnnyMaynne]

Hello everyone 😊

Please help me because I just can’t understand why I am receiving this data.

Here is a list of my records sorted from oldest to most recent:

As you can see, there are only 9 records and all of them were created in August from 09 to 18.

During this period, 2 records were deleted and this can be seen in the statistics.

So, requesting the following data:

I get this result:

So here it is. Why do I get the value 5? After all, at the end of the period I have 7 entries, the same thing will happen if I try other types of grouping.

Even if I choose to group by day, the value will still be 5.

No ideas?

The logic IMHO is:

Although 9 events of type HeadCountStats were fired in the period above, the state of "head counts" is 5. You had 7 "head counts" for a while, but 2 got 'deleted' so the rest is 5.

In Event Sourcing, the events change the state of something and this package is a simple implementation of this technique.

If all events had been "HeadCountStats::increase()", the "value" would be 9 for that period.

Логика, ИМХО, такова:

Хотя за указанный период было запущено 9 событий типа HeadCountStats, состояние "количество сотрудников" равно 5. Какое-то время у вас было 7 "подсчетов голов", но 2 были "удалены", так что осталось 5.

В Event Sourcing события изменяют состояние чего-либо, и этот пакет является простой реализацией этого метода.

Если бы все события были "HeadCountStats::increase()", "значение" было бы равно 9 за этот период.

Based on this logic, the data that the packet generates is incorrect, because it should not just be the sum of all events for the period

I would like to join and help, but I don't see any problem here. Data seems correct. What would you expect the data to be given your inputs?
