IS IT A PINT?

An independent study measuring whether American bars actually pour a full pint. Most 'pint' glasses hold only 14 oz. Data, methods, and the Pint Patrol app.

I'm having trouble understanding these 2 claims from the summary:

> 1 in 2 pints delivered less than 14.4 oz (below 90%)

> 37.9% were significantly short (under 90% of claimed volume)

Aren't those the same claim with different percentages? 1 in 2 is 50%, and 50% is less than 37.9%
