The angle is read the other direction. It's not what country you're from. The angle is read from the vertical axes. If you look at the test itself it prints with the degree marking on the back for each area it prints to help you understand the angle. Since you obviously didn't print the test you would have seen the angle indicators.
There is no 15 degree or 85 degree marking... Lol so what did you use to test?
It sits higher but the air is pointed downward. It does not push air more at the nozzle it actually aims the air towards the tip and downward.
