CT ECM codes

[Fleetman13]

I was messing around on CT today and was curious if their ECM code numbers were like insite…For example in insite your ECM code is HD10218.19 and the last two numbers is just a newer ECM code calibration. In CT I have a 60.70.17.70 which should theoretically be the same as HD10218.19 in insite. So is CT code 60.70.17.15 the same base code but just an older version of the calibration?
