It depends on the value of x. I think it's safe to assume x <= 0.75, else they'd contribute negatively to their teams (happens from time to time, but let's be generous). Previously they'd be anywhere from a 0/10 to 3/10 programmer, and now they get up to 9/10 on a good day but sometimes are a net negative, as low as -2.25/10 on a bad day. I imagine that happens when tired or distracted and unable to adequately police LLM output.
