Pix4dSurvey automated feature extraction success improvement?

May sound like a silly question but would the higher the resolution of imagery (i.e., closer the drone is to the ground it is surveying) improve the automated feature extraction tool success rate? Currently have data flown at 65m which is yielding good results but would 50m survey height improve this?

I think this is more of a function of the density and quality of the point cloud. It is possible that flying lower could help but you might also want to consider flying with more overlap, too. I would try more overlap first.
