If for whatever reason I am not content with the way i did my wiping of the feet or head, whether it be because I have doubt that I did it correctly or some other reason.

Can I repeat the process of the wiping? Must it be done once? Or should you restart the wudu from the beginning if the sequence is important?

If you are not certain you wiped correctly you can wipe it again to make sure you are certain. Once you are certain you should not do it more.
