Counting practice
Right now I am practicing the Zen count, and I can count down a deck in 30 seconds, one card at a time. Should I practice counting two cards at a time? I know some cards will cancel out and give a count of 0, however, some cards will create a two card total of 4, 3 and -3 and -4. Is it necessary to practice counting two cards at a time for a level two counting system?
