Have played Hiopt2/ASC and Hiopt2/BASC with players that play other systems including Hilo up to level 3 systems. There are always a good bit of difference in advantage assessment. With a hilo player there was a lot. With a level 3 count with 1.0 BC player there was much less difference, except he always raised his bet earlier and lowered his bet earlier. Relatively we assessed advantage pretty similarly. Not so much for Hilo. Often the Hilo better bet big when I assessed a disadvantage or bet minimally when I assessed a big advantage.
