Take-home: perceived uncertainty about future rewards is related to higher delay discounting. This appears baked into the task even when specifying that rewards are 100% certain.

Reward delays are often associated with reduced probability of reward, although standard assessments of delay discounting do not specify degree of reward certainty. Thus, the extent to which estimate...

Plenty of variability within cultures, too. So unless someone on the committee knows the letter writer and can help interpret the presence or absence of hyperbole, it's like reading tea leaves. Quantitative ratings would be more informative in most cases.
