SBUX - Bearish Weekly RSI

I have been seeing this Descending RSI pattern that leads to a break upward followed by a down correction back to the descending trend line
This is showing again on this RSI for SBUX, I have used the dotted green line to show how I estimate the RSI movement to occur.
Last time this dump happened it dropped 75%. Assuming the same drop of 75% this leaves us with a bearish Weekly chart.
