Both of your tests are consistent with what I found (see above) -- although I curiously only get 30 voices in panel A, but often get to 28 voices in panel B... Did you use Panel A for the single-panel test, or did you try both?
In any case, the polyphony is quite close to what has been advertised, I think. There may be some specific conditions that are required to get to the full 34 (or whatever number is in the manual).
