Like for the same reason we try to find out where stock price is heading ahead of time... Sometimes the two seem to be related.
Just ignore if you´re not interested or don´t trust the source, constant nagging about that doesn´t help anyone.
I wasn't nagging just asking a question, I do follow him on X and appreciate the work he puts in and trust him regarding the numbers, but I would call it tracking rather than estimating. I don't agree with some of the conclusion he draws e.g demand being limited and find it overly negative sometimes.
