Monthly variations in sentiment surveys tend to be minor and volatile, much like the variations in spending patterns that they foreshadow.

情绪调查的月度变化往往很小，波动性很大，很像它们所预示的消费模式的变化。

However, while wary of general guidelines, Dr Elliott-Sale sees the merits of an individualised approach which takes account both of monthly variation within an individual and inter-individual variability.

然而，尽管埃利奥特-赛尔博士对一般指南持谨慎态度，但他看到了个性化方法的优点，这种方法既考虑了个人内部的月度变化，也考虑了个体之间的差异。
