I've always shuffled three times due to hearing at some point in my childhood that 3 times was the max amount of shuffles needed to completely shuffle a deck. Recently I realized that doesnt check out but it's been hard to break the habit as more than 3 shuffles seems to take forever. 7 though? Wow.

With practice you can get a riffle under 2-3 seconds without weaving. But if 7 still seems too much, do less but do a running cut or overhand shuffle between two of the riffles, like riffle -> riffle -> running cut -> riffle -> offer to cut -> deal. I heard this is what casinos did in older times, and they do have a direct interest in not making the shuffling too long (less hands played) or too weak (can be abused).
