I understand your concern. Haejin calls things as he see's them. And you're looking only at weekly time frames. Projections always change, it is very rare that anything plays out exactly as you draw it up, unless you're in a super bullish phase within a bigger bullish trend, which is what we've experienced lately. But with extended and complex corrections, time is impossible to gauge.
Additionally, with say, your First Blood chart, Haejin is expecting that downward movement. Descending channels that form the handle take on average anywhere from 4 days to 2 weeks in these long developing patterns dating back several months! He is simply giving us a heads up on certain possibilities and it is on us to figure out when and where the opportunities lie. Good luck!
