skyeci before you was g.inp you was interleaved, so a sync speed increase is no surprise, it will very likely also see an increase on the 8800nl, but by the same amount? you wont know until you try it.
Its very important to check for and specify here if its apple vs apple comparison, apple vs apple been fast path vs g.inp.
Managed to try the billion out tonight. It synced lower than the eci but latency was the same. Some difference in snrm values between the 2 modems.
Billion synced at 62 where as the eci synced at 66mb. Went back to the eci 40 mins later and it synced higher than the 8800nl, just shy of 66mb. Maybe the eci modems do sync higher....
So far for me the billion synced faster than eci pre g.inp but with high latency. Eci wins after g.inp for sync speed. Latency appears to be the same post g.inp at 11ms
