Tested. Repeated imports/export/import... etc., of a demo project, will create identical exported midi files and identical imported mmps. Volume <-> velocity is correct.

According to MIDI 1.0 specification, which might be this one, velocity is not strictly defined, but it should follow a logarithmic scale. I guess velocity = 64 should mean 100% in LMMS.

velocity is not strictly defined

Correct. It's basically just info about how fast a key is struck.

I guess velocity = 64 should mean 100% in LMMS.

And it is. (had to double check...)

Sure, 100% is 64. I was suggesting to consider a logarithmic scale instead of a linear one.

Should we use the algorithm from our favorite free MIDI player?
