Dear Curioso,

Finally, I think I have a basic understanding of the XARD system now, but I still have one question:

• Please check the screenshot below.
  How can I avoid this type of issue and identify when it's a fake signal to prevent it?

For example: A. How many mini-dots should I wait for, especially since sometimes it works after 2 dots, 4 dots, or even after one big blue dot and pink dot?

I believe if I get a clear explanation of this, I will fully understand the concept. As you said, I do grasp the overall elements as you’ve mentioned.
