Yes -- using hemoconcentration/dehydration alone to explain 2.8 (or 3.6) in 2 days is ridiculous no matter how you slice it.
What then, is a good "maximum" upper bound?
If we assume a maximum 10-20% plasma volume loss, and do the math (I leave that to you), I guess we would find something less than half, surely not more than 1.4-1.5.
You really should include not only that Paula ran harder, but also the following differences of the 10 - 20% experiment done also around 22 C, where:
1) The participants ran 2.5 - 3 hours (vs. 67 minutes).
2) The participants didn't hydrate (while Paula used a scientific approach to always hydrate perfectly in races).
3) The data were taken directly after the run, without rehydration (while Paula rehydrated for 60 - 90 minutes).
In conclusion, I would divide the found maximum of the 20% hemoconcentration by a factor of 3 or 4 in this case. But ok, let's use a factor of two to give ensure the avoidance of a false positive -> maximal possibility then is a 10% heme increase for Paula -> here 1.20 g/dl.
That brings her from 12.0 to 13.2, far below the experimentally determined 15.6 g/dL.
As for the "expert" - not experts - saying otherwise: this person a) really has no credibility, and b) presented no reason for his conclusion. Same goes for the infamous "bloated" IAAF defense document, wherein they basically say that hemoconcentration is possible and therefore the increase is possible, without demonstrating that the numbers do work out.
Apparently you struggle with the last part too, rekrunner, which is why you started to invoke extreme measurement errors. Those in turn are not mentioned by either IAAF or Saugy in arguing for the plausibility of the 3.6 g/dL increase. It is also obvious that they ignore the 12.0 value, exclusively talking about the 12.8.
