I make it five shots too, since the multi-exposure function is additive the post of the turbine would make overwrite the foreground bushes so I guess it's all the one scene. Maybe the perspective makes the height deceptive and often standing below there is little breeze even though the turbine is spinning at quite a rate. From recollection wind speed at 35 metres will generally be at least twice that at ground level, most turbines are at least 25m above ground.
