NOVA! Sorry coach belly....had to get that out of the way.
So if the aces were randomly distributed, then yes the player would have an advantage during that high count clump. And cutting such a clump into play, like at the front of the shoe would be advantageous. With a human shuffle, keeping the aces separated would add another layer on complexity. It would take an expert mechanic to pull that off.
But with the ASM situation the aces are not randomly distributed. They always end up clumped with the low cards. Again, the machine has that capability.
