Lowest point in space for big toe, small toe, and heel

[Edward Lannon]

Hello,

I am trying to find the lowest point in space in the big toe, small toe, and heel from data extracted from open cap recordings. I am looking at the marker data files using the 2D key points and they are quite different when I try and find the max Y values. You would think that they would be similar since they are coming from the same foot (R). Which one of the listed would you say is the most accurate?

Thanks for the help.
