4 HP is within the margin of error for any dyno ever made.
You lose more than 4Hp on a hot humid day.

The interesting thing about this confirmation is that the Subaru spokesperson said the spec sheet was accurate.

Does that mean the 13.5:1 compression is also accurate?

Its an interesting situation.

Generally speaking, an engine loses three percent of its rated power for every 1,000 feet of altitude gained.

@200HP, 3% is 6hp...

Also:
The change in horsepower is proportional to the inverse square root of the ratio of the two temperatures. This represents a 1.02% increase in horsepower. If the engine was producing 850 hp at 77 F, it would produce 867 hp at 57 F

If they ever spoke to a "spokesman" and if they did they even had a clue what they were talking about.
Their "spokesman" they quote so often has told us there will be a turbo BRZ every year since 2015.

You mean "chassis dyno", right? I'd expect an engine dyno in a manufacturer's R&D lab to be that accurate and with their ability to control variables I'd expect they could do repeatable pulls with less variance.

Aren't horsepower numbers usually a little different in different markets because of fuel and emissions? Isn't the ECU different? Sure, they usually issue a blanket power spec worldwide but isn't that not quite accurate? So long as power isn't overstated it's accepted that especially among certain makes(Porsche, BMW) the stated power is not correct.
