I did some research on Ace-Sequencing, but I just cannot understand how people are able to count and shuffle track simultaneously. I read that unlike counting, shuffle track is much harder that while many people can count but only some are table to shuffle track.

I originally use Hi-Opt2+ASC, and I tried doing it with Ace-Sequencing. I know everything needs many hours of practicing, but for now I just cannot believe that some people (unless they have photographic memory) are able to do both simultaneously.

Any advice?
