As it is labeled, it is what the manufacturer guaranteed and what was accepted by the customer.

In perfect world: sure. In our world and especially during the war: no.

Again - 500 +- 5% means they tried to achieve 500 but it was more likely that most of the time, they made it closer to the -5% in so called real life. I am not saying that they were failing to stay within margins.

Oh yes, please read again what I wrote before, thank you.

A very thorough inspection is completed before the first test flight. The manufacturer will put the aircraft thru a test flight period to ensure it reaches its numbers before turning it over to the customer who again goes thru their own prescribed regiment of test/inspections before accepting it.

When an airframe reaches the end of the assembly line, it was not uncommon for it to remain there for a month or so as it was tweaked and refined before being accepted.

Of course, I don't disagree at all, this is all well known facts and we can go as far as comparing the later 109 models leaving various factories. Of course there was a difference and variation in real life. The question is what data to use in order to have the a/c close to the real life performance. My opinion is that manufacturer's data should be considered as on the optimistic side.
