Improved connection since firmware update

I'm wondering if anyone else has noticed an improved connection since the cab/modem update? I've had interleaving removed but my sync speed hasn't gone back up as far as it used to. As a result (it seems) my modem is holding the line better:

I've had interleaving removed before but my speed was usually in the low 70s and interleaving came back after a couple of weeks. There's also obvious packet loss during that period). At the moment I have no noticeable packet loss.

Quite a bit more on that on

I had interleaving removed. My max rate dropped a fraction, but that was more than compensated for in reduced error correction, so my sync went up (from around 70 to around 77)

for me and some others on kitz forums its worse.

I sync at the same speed, which is surprising given various tones get turned off by this firmware, but I have a error rate of about 300% over the previous firmware, and the first couple of days the error rate was almost 10x.
