Yes. The table shows 33 l/min for 3 crew and 44 l/min for 4 crew, so it's clearly 11 l/min per person at that altitude.
Also, about the « note », do you think that we must add the figure of 13 L/p/min to the 11 L/p/min. of Table 2 (new consumption : 11 + 13 = 24 L/p/min.) or this first consumption (13) replaces completely the latter (11) ?
Table 3 gives what needs to be added to the table 2 value for extra time. I understand the "add" in the note the same way. If you read it as "add to table 3", that would more than double the oxygen requirement, and that feels implausible, and would far exceed the air density difference? But I could be wrong on that, so hopefully someone else knows better.
