Most literature I've read states that, at a minimum, you need to be able to count down a deck in under 30 seconds in order to count accurately at a casino, and that you really need to be under 25 seconds. Well, when I was learning to count, I never tried to get my time under 30 seconds when counting one card at a time. Once I was able to count down a deck accurately several times in a row, I immediately graduated to counting two cards at a time. Once I was able to do that accurately, I started focusing on getting faster at doing it. I can now count down a deck in 20 seconds when using two cards at a time, but it takes me 35 seconds if using one card at a time. Is that normal, or am I abnormal? Is it acceptable? I welcome all advice and criticism.
