The point is that the "combined" dating is a methodological flaw in the situation when it is not certain whether all quires were produced all at once. Chances are they simply were not.

How big are these chances?
The same people who said that parchment is typically used shortly after production, said that book production would typically not span a very long time. This is only briefly hinted at in the report, but it was at the basis for the decision to combine the measurements.

I imagine that there are exceptions, but how rare are these? Fewer than 1% of all books?
Anything of that low probability will not change the result.

Do not forget that:
- the probability of being outside 1404-1438 is still almost 5%. Anything of significantly lower probability will not play a role
- 1404-1438 is probably comparable to a typical 15th C person's professional life

Now it would be a methodological flaw to give particular weight to one sample, if we know in hindsight that it slightly deviates from the other three. This is especially true since this 'slight' deviation isn't a deviation at all, as all samples are within each other's 1-sigma error boundary.
