Linestats and interleaving...

So apparently my connection was reset a week ago and i hadn't noticed, i checked the linestats today out of curiosity...
And firstly there is now Bearer 0 and Bearer 1
Bearer 0 has interleaving depth of 16 on downstream and G.INP enabled...I can't think why, the only time there's been any bursts of CRC errors is during a lightning storm and that didnt cause any disconnections...
It's a bit concerning as I cant see any reason why interleaving has been enabled

http://pastebin.com/NLx8jzit is my linestats from ~1month after I was enabled

http://pastebin.com/1qsfTuAh is my linestats from just now after a modem reboot.

Any ideas anybody?

G.INP is good news not bad.

when it was seemingly uneeded/coupled with interleaving? :|

The interleaving effect becomes unnoticeable with G.INP. Normally set to 8/1, and Delay set to zero. So no loss of sync (0.2kbps or 0.2Mbps IIRC), and no addition to latency instead of the initial 8ms value on normal interleaving.

Yet I'm 16/1 for depth on (bearer 0) and delay 3 (on bearer 1) on what was a seemingly very good line...

That's what I'm confused about, why the depth/delay on a line like I have? Which had low CRC errors (50 per day), good speeds, no disconnects...

Since I last rebooted the mode there's been no downstream CRC errors though...still, I can't see why G.INP was enabled with this delay/depth
