Thank you for clearing that up for me! First, I apologize if my reply has hurted anybody's feelings in any way. By "stereotypical belief" I called an attitude like, "it is just not possible" as a response to my logical search for an answer. People have their rights to have any opinion they want to have, however, an apparent reluctance of considering important (from my point of view) new findings, shown in several responses, I consider as "stereotypical". No offense meant. And by considering I don't mean "agreeing", I mean using logic and evidence to prove me wrong. And I hugely appreciate your help, Grisu, in finding the truth! Thank you for your messages in this thread - it is an invaluable assistance in the search! As for the Shuffleblast's second statement, I did not ignore it. I just don't feel it is right to state for the third time in this thread that I totally agree that 2000 runs is not enough, but that is all I have right now. I can not jump in with another 10000 runs (which will not also be enough) because I don't have them. Or, I could have kept silence about the IP SC in the first place, but I chose not to. It was my decision because I consider these findings of huge importance, if it is confirmed. Second, I do not care if people agree with me or not as long as the truth is established. I might be wrong, I might be right. If my theory is correct - then it will be a "revolution" in HR hunting. If not - I am just another victim of the RNG. Frankly, I don't care that much about the final verdict, as long as we go along the path of finding the answer. That is the biggest kick ever! I am a researcher by nature and by my profession and I approach every task I encounter from this perspective. After all, I got back to D2 (profoundly) last year with the only challenge of beating RNG in LK, but that is another story. So, I hope that those who share my attitude to this issue will cooperate in finding the true answer for the observed "IP SC phenomenon". I would suggest at this point that the mathematical hardcoded algorithm that defines yes/no answer for EACH TC (including runic TC) for any game object that could drop (chest, monster, etc.) includes several parameters. One parameter belongs to an object that drops it (hardcoded), another is general for the object that is being dropped (in the files), and there might be others. For Blizzard this is a simple equation, like A=b*c. You take b from the files, you take с as a hardcoded parameter that goes affined to each potential dropper. I don't see any trouble for Blizzard at all. As for "why" - the answer is, to have more freedom in varying "identical" objects, for example. Like sparkly chests of the same area, or bosses of the same level. Why not, when it's so easy and handy?
