My small run of experiments leads me to believe Suntour and Shimano actuation ratios must be very close or the same.
I've run a Suntour Superbe Pro rear derailleur (84ish) with indexed Shimano shifters and 7-speed Shimano cassettes for 8 years with no issue. I've used indexed XT m730 thumbies and XT m739 rapid fires.
I would be very interested to know more about Suntour's actuation ratio as I have a lot of old Suntour stuff and I love it - except for the shifters and cassettes.
