Horace,
I think Lewan's thinking is the following:
- the system is more or less at steady-state
- the flow into the T-tube (let's call it 'outlet_overflow') was (more or
less) constant,
- the liquid water coming out the end of the HOSE was then:
Outlet_overflow + condensation_in_the_hose

I don't see how it is possible to get reasonable measurement using
the T-trap. If you look at the film at around 3:50 you can see the T-
trap is full. If you then look at 4:25 you can see the flow is very
fast, and could fill up the T-trap in a few seconds at most. A small
plastic container is being used by hand to capture the flow. Likely
that was later weighed.
Here is the film URL:

Here are the notes regarding water overflow:
20:50 Overflow was approximately 3,7 grams/s or 13 kg/hour. T2=29.3°
C, T3=90.3°C.
20:55 Overflow decreases. T2=29.2°C, T3=93.4°C.
21:50 Liquid water at the outlet was measured and found to vary
between 1.4 and 1.8 grams/s or from 5.0 to 6.5 kg/hour.
So, it was not your imagination the overflow was measured. My point
(see below) was merely that the T-trap could not be used to make the
overflow measurements, at least not accurately. Measuring required
removing the hose and using a container to catch the flowing water.
Very inconvenient to do frequently. The T-trap was highly under sized.
