Personally, I'm not optimistic that both or either He Bingjiao or Sun Yu can do well in back-to-back SS tourneys, not at this time yet. First, neither of them are particularly fit or have the stamina and endurance. Second, neither are experienced enough to know how to pace themselves properly throughout a tournament and then immediately the next which also requires strategising according to the opponents along the way, conserving energy as necessary and making correct adjustments as the situations unfold. Even so, the best of plans go awry and the unexpected often does happen as when a particular opponent plays especially well or manages to stretch you to the limit in a long,grueling war of attrition.
I'd be satisfied at this stage if both and/or either HBJ and SY can at least advance to the QFs, anything more is a bonus. But I certainly will be expecting much more of them in the near future. There's no shortcut to success, they've to take one step at a time; they would be lucky if they can skip one or two steps to reach their goals quickly. Li Xuerui is a phenomenal exception but look at the price she paid for it, immense pressure, nervous tension and injury-prone.
For me, a gradual and steady rise to the top is much more preferable, and ,I believe, would last for a longer duration, unless you're truly exceptional which very rarely happens; most tend to rise suddenly and fall just as quickly.
