If you play a set strategy over many 1000's of hands, then your stats will be very stable.
If you are playing 8 tables, it's much easier to play every hand mechanically rather than think about it. The delay in actions is explained by a real person 8 tabling.

This is kind of a reverse Turing test. A "Turing test" for artificial intelligence is that if you ask questions blindly to an AI program and a person, and you can't tell the difference then you have achieved "intellegence".

Finally - if you could write a program to play like this (and probably you could) then you certainly could PLAY like this.

Question is, what difference does it make? If they are telling the truth, then there is clearly nothing wrong with this approach (other than dying of boredom). If they are lying and it is a bot - so what! It's been shown to be equivalent to 3 guys in their undershorts playing unimaginatively.
