The more time at one price, the more time for a rally.
Once the market 'disconnects' from a 'mode', then count that many days forward to project a time to exit the trend.
Once the rally time expired, a new consolidation had been building which was a smaller 9 days. The market disconnected from that price and is now in the final stages of the advance from that 9-day consolidation set to end this Friday, October 3, which is 3 trading days from now.
This method was very useful for calling the top in TSLA earlier this year and many other markets.

GPRO hasn't really established a foothold in the mid 70s or the low 80s for that matter - it just shot through these levels without much consolidation.
The volume over the past two days has been huge. Notably, today's daily volume was over 30 million shares, but the price of the stock hardly budged. Additionally, it closed below the open price - first significant close in my opinion of this nature in the past seven trading days, given the associated volume surge.
If it pulls back earlier then you anticipate, do you see a potential scenario like TWTR or PLUG playing out here? Recall their climax runs. I believe TWTR dropped $15 in two trading sessions. PLUG lost half its value.
