Glad you felt up to admitting to this.
I long ago became convinced that there is an effect to the vertical POI as a result of strong winds. I found this out when Cornwall FTC was based on an old mine site on a 600 foot hill with line of sight to both the Atlantic and the English Channel. The firing points were reasonably sheltered but downrange was open to the full effect of the wind.
Finding the pellets being pushed up an down as well as laterally was not unusual.
