What's everyone getting for those of you with interleave on?

I am usually getting 16, delivering 900kbps.
However late at night or early in the morning like today, it sometimes connects at 32 and I'm getting 1600kbps with no crc errors.

Does anyone know how this is set, or actually, would calling Ogero and asking for it to be set at 32 get the job done?
I connected my modem to a ups and it kept at 32 / 1600kbps up until around 2:30pm. Then the CRC errors took over, restarted and it was good old 16 / 900kbps again.

I'm guessing the backbone can't handle all the users. Just %$?/!$% great!!
