Since he did not seem to learn from the low end term he previously received, I suspect a high end term is far more likely. I don't know where you get the four year term from because it is not contained in PC 261.5 or PC 18. There is a four year term for a relationship with a girl under 16, but that's 2, 3, or 4 years without the 16 month option.
The prison term for a consensual encounter between a 17 year old girl and a 25 year old guy would appear to be 16 months, 2 years and 3 years, by a fine, and a possible civil assessment of up to $10,000.
