No attempt is made to perform high resolution modeling of separate wind and current forcing or leeway modeling to predict the resultant differential movement due to the different sizes of individual pieces of debris.
The above caveat is important in understanding the results obtained, i.e. no allowance has been made for the way the Flaperon floated, or may have been influenced to a greater extent than an average debris piece due to wind.
Until such time as there is a better understanding of how the Flaperon floated, it may or may not fit neatly into this study. I personally suspect that its behaviour will fall outside that of a general field of floating debris.
Time will tell.
