Hyperspeed Grinding
Hyperspeed Grinding (HSG) is a hyperspeed technique where Mario can continually gain speed by staying in the air while grinding.
Execution
HSG is usually performed by grinding on a moving or sloped surface while held in place by a wall.[1]
Uses
HSG was used in the A Button Challenge to gain enough speed to jump-dive and skip multiple problematic parts of TTC.[2]
