SunTour hastily engineered AccuShift and got it to market for 1987 but it was far inferior to SIS. They immediately went to work on 2nd generation Accushift of which Olé was part and introduced for 1989 (maybe 1988-1/2). It was much improved and, depending on your view, on par or almost on par with SIS. However, there were still some 1st generation Accushift groups in 1989 that didn't get upgraded until 1990. So, when you're comparing Accushift and SIS, you have put it in context of the group and year.
