s_opt is the variance of different optimizer runs. MultEval is intended to deal with optimizer instability, and is most useful if you run your optimizer (e.g. MERT) multiple times, and create multiple hypotheses per system. With only one hypothesis per system, there is no way to calculate optimizer variance, and you get NaN for this field.
