Strava would have no information about either drafting or wind direction. So, if you're drafting, it should estimate the power high, and riding into a headwind, it should estimate it low.
If it routinely is off, perhaps the conditions of your ride just brought it closer to reality.
It felt like the whole ride was into the wind... In reality, unless the wind shifted I'm guessing about half was.
