Suppose we have a random service time $T$ with residual service time $R$ observed at some point along the way.

What is the correct way to call $T$ (in 1-2 words, without having to introduce $R$) if:
1) For any observation time, $\mathbb{E}R\leq\mathbb{E}T$?
2) For any observation time, $R<T$ in distribution i.e. $T$ stochastically dominates $R$.
