Oops the 3 seconds one was a typo :)
Ok with .wav it seems to keep consistent timings.
However, using lame "straight" (lame.exe) results in the following timings:
(and the files stay the same size, so maybe lame has fixed their
problem since then?)
This is using the same version of lame that ffmpeg is compiled with.
