Wouldn't worry much about the deltas, or predictions, until you are more familiar with reading Q drops yourself. Everything about Q is ambiguous, subjective and open to interpretation, until reality proves the interpretations.

In the meantime, try the Q section of https://www.martingedd.es/patriot#/compendium/ for well-written summaries. I also recommend the decoding symbols guy (https://decodingsymbols.wordpress.com/blog/), not so much for specific drop interpretations, but to get a feel for the multiple communication types and purposes carried out by Q. Poke around to find his posts lustre by category, and look at the Q-related ones. Also the first "Law of War" video, because even though he looks crazy, he absolutely identifies a legend for reading an important sequence of Q drops.

Q is certainly real. The specifics of who, how and when are open for debate. The what and the why are better defined, even if there are blurry boundaries. But you are free to interpret on your own. Fresh perspectives are always welcome.
