I undertook this some time back, I might be mistaken, but starting from beneath your privates, measure straight down to the floor. then take that measurement in centimeters and divide it by your height in centimeters. usually, that ratio is .46. You need to approximate whether your increased height will exceed 0.49. I think that exceeding 0.49 or reaching 0.5 would appear unnatural concerning the proportions between legs and torso. For instance, mine shifted from 0.46 to 0.49, which is the upper threshold of the leg to body ratio.
