tickets/DM-199: Develop new master-worker result system

In my opinion, the control flow would be much easier to read if it went like:
```c++
{
    ...
    if(_tableCount == 1) {
        bool isOk = ...
        if(!isOk) {
            ...
            return false;
        }
        return true;
    }
    // Don't know how to handle things otherwise.
    return false;
}
```
