Aside from pacing better, if your cadence drops to 40rpm for too long and you are in your lowest gear at maximal effort for the expected duration, then you could probably use at least a gear 2/3rds or less than you currently have so you are likely to be able to sustain closer to 60rpm. That's possibly not feasible on your bike, but perhaps a 29 rear cog at ...
The short and most direct answer to your question is to use your power meter to pace your ride optimally and Alex Simmons, who has given another answer to your question, was too modest to mention that he is an expert in this and has developed one of the most sophisticated power pacing models for variable conditions. A longer answer is, to paraphrase Prof. ...
Bad data, no question whatsoever. Muscle fatigue develops quite rapidly, but even so there is minimal decrease in power for at least a handful of seconds. (Indeed, even the fitted curve you've shown seems to be in error, likely as a result of the way GC's fitting algorithm will chase "noise".)
Putting aside the crank fitting problems, you can forget about using data from a Stages power meter for reliable neuromuscular (very short duration) power assessment. It's simply not suitable for that task (not many power meters are).
