I started to work with the data I got from Li Liu. I have no metadata file, so I am not sure what will finally come out of the analysis.
What is already clear is that the number of female and male they tested seem different for each group and there is a big difference in speed between male and female… The value reported are also huge (>20 mm/s, no distinction male/female) while I get the normal 15mm/s (if the data I got is in mm and not in pixel, of course).
I do not know what GAK and ‘PAN stands for…

speedplot from liu data. X axis is not explained yet. homogenous environment, platform is 86 mm.

Remember that from our data, there is no significant difference in male versus female speed.
