General DiscussionCalibration calculation

i got idea . when u want to calibrate .. play normal match and then see in dota buff which brack ur in .. if ur in normal or high skill .. dont calibrate first until you are in very high skill so you are not in the retard bracket .. and 1 more thing , they record ur normal match too .. so dont calibrate until ur in VHS bracket

all 3.. but depends on the role.. other factors could be kill participation, support items bought, rosh kills, wards placed. behavioral score also helps in calibration
