FEV1/FVC Ratio is over 80%

Hey guys, there is a question in UW (id 825) that talks about crest syndrome and pulmonary hypertension but then they mention the fev1/fvc ratio is 86 so since that is higher than the normal (80%) i assumed there was some restrictive disease but apparently 86 is also normal?
Everywhere I searched it says normal value should be 80.

Any input :(
