Don't tell them what they've already seen. Next time you think about saying "So, I've just shuffled up the pack," stop yourself. Just stop. Think about what they've just seen. You throwing in a bit of a not-so-subtle remark about what YOU have just done isn't subtle at all. Speak less, do more. Also, when I say "do more" I don't mean to do more. Find your balance.
For the record, I'd never do this sequence of shuffles together. Hell, I wouldn't even shuffle this much in performance but that's what practice is. Stick to one that's best for the scenario you find yourself in. Just please don't tell them what they've already seen.
