this particular argument ( or this pointer) should be regarded as a real funtion argument, or not?

Yes, the 'this' is a pointer to the instance data for the object and is normal for OOP. Without it the best the code could do is access static data for the class.

but based on IDA, we notice another instance of the same function is called with only one argument (i.e., the last argument). I guess the F5 analysis is not reliable and not consistent.
