We all rely on guidance mostly, and frankly it's all subject to change esp beyond day 10. Things that were 'supposed' to occur at one point, a few days later might look quite different, more so when we are clearly moving out of what was a sustained pattern to something else. Models sometimes struggle with where exactly it goes going forward. In this case the volatility its mostly related to uncertainty with Nina induced forcing in the tropics. This sort of thing causes the mood in the LR thread to often resemble a sine wave lol.
