I'm not forwarding every mail from LAD, but this one might be important too. Run it with the -w and -r option, perhaps this might be the right way to do it.

I wonder (but haven't checked the source) why the tool even starts when you don't provide the value for the wait time. Niels, you need to re-evaluate everything, too, your data is also aligned to USB frames as pointed out by Clemens two days ago. I use -w 20 -r now, alsa-midi-latency-test then prints out a message like "interval between measurements: 20.000 .. 40.000 ms".
