TLDR: I am attenting a seminar where the grade is based entirely on a talk I hold. The responsible lecturer fell asleep during the talk multiple times, and I am worried about my grade, feel insulted and am unsure how to communicate these issues.
For a seminar, I was required to hold a 45 minute-talk about current department research in front of the course. The corresponding researcher attends this talk as well.
Together with the lecturer (the instructor for this seminar), they grade my talk, which amounts for the entire seminar grade. The researcher can make comments about how accurate the presentation was, but the ultimate choice of grading is with the lecturer.
During my talk (actually not too far in), the lecturer fell asleep for a bit for the first time, for only a brief period. Now this happened on multiple occasions during my presentation, and it has happened during someone elses' past talk on an earlier date as well.
I find this highly insulting, since I have spent a lot of time reading up on the topic and practicing to hold the talk.
Since the lecturer did not hear or see my entire talk, I am worried that grading may be affected in addition.
The lecturer is notoriously busy (which I assume to be quite common) and stressed, but both issues should not affect me or my grade in my opinion. Also, he may have had stress-related health problems in the past, which could be a reason for him to pass on caffeine consumption. I see that this may be a reason for his tiredness, but again I cannot possibly account for it and I should not be graded differently because of it.
I want to communicate the following two issues, how can I approach this situation?
I feel insulted by the lecturer falling asleep through my graded talk
I am worried about him falling asleep could influence my grade
On a side note, I really like the lecturer otherwise, but I am afraid that making a comment like "please reconsider your sleep schedule" whould be considered highly inappropriate (and rightly so). Recommendations on this matter will be appreciated as well.
Update: Grades are out as of today, and I am not satisfied with the grade. I don't have any pointers on what I could have done better or how to improve future talks. I will probably not pursue this any further.
I don't know if I wrote this in a comment already, but in another seminar I attended, a similar thing occured for another student.
