I had some of the same experience with early varieties like Yukon Gold that hilling them is not going to make more tubers along the stem. Their growth habit is determinate and the tubers are close to the main stem. Some later varieties would send stolons along the stem producing more tubers so they benefit of extra hilling and I had others that send stolons far away from the main stem so a wide row benefits them. So far is a trial and error when I try new varieties I hill them to see if they are determinate or indeterminate.
