Yes, that's it.
It's a case of remembering sequences of cards which culminate in an Ace and knowing the effects of shuffles on their placement when next dealt.
The best method of doing this for more than an Ace at a time is to get some sort of memory training.
There are online courses available. Type in 'memory improvement' in your search engine and see what it gives you. You don't have to spend money on a book or tape course, the information you need is all available free.
It's well worth doing although last time I posted similar info it didn't get any intelligent response. The only effective Ace Tracker(ess) I knew used the memory techniques you'll find in these courses.
It's a powerful tool once mastered and well worth the time spent.
