And Burakkucat’s line is rather faster than mine at 2.7-2.9 Mbps d/s sync , so if his bins / tones don't go high enough, then mine certainly won't.
One line, cwcc@a.4 is slightly faster downstream btw, at least most of the time.
But for some reason the line tested here, cwcc@a.1 is always the fastest upstream by a sizeable amount, the upstream differences being a long-standing mystery. (I can't even cook up any candidate theories for why.)
One other problem with the weak statistics of these tentative results is the variation in the SNRM. The reported figures might well just be strongly correlated with the sync speed. In that case, the question is, what about the variations in SNRM within one mode? (where say lower SNRM is linked with higher sync rate.)
The results presented are in time order. One bizarre outlier, at 200k d/s sync below the normal range was stripped from the dataset in calculating the derived statistics as an anomaly. It was perhaps to do with its being the very first result obtained (soon) after power loss, or perhaps after upsetting BT somehow.
If anyone speaks stats I would appreciate some help. Utterly ashamed to say never got my head around the subject properly, but amazingly Theoretical Physics students at my place never got a course on the subject (well perhaps that is for the experimental lot).
