While mathematically, your logic is sound, the answer is almost always no. Basically, they’re not going to measure everything out. 3.4oz (or 100ml for simpler numbers) – what if you have 98ml or 95ml? They don’t have the time or the inclination to measure all to say ‘yes you’re under 100ml’. As a result, it’ll be on the bottle size.
Source: personal experience, when they’ve confiscated multiple almost-empty bottles from me 🙁
Also:
Liquids, gels, and aerosols must be in containers that are 3.4 ounces
(100 ml) or smaller. Note that larger, half-full containers are not
allowed.
and:
Note, the container itself must be 3 oz. or less; a 4 oz. container
that is half-full will not be allowed through the security checkpoint.
