YB Tracking Gain
In YB Tracking tables, there are various columns, mostly self-explanatory. However, one column is Gain, obviously a comparison of change from a previous point. But what point:
a) The relative positions from the last YB download that you made on the reference boat i.e. calculated by Expedition?
b) The relative positions from the previous YB download, even if you did not download in on the ref boat i.e. calculated by YB, not by Expedition?
c) Something else?

Re: YB Tracking Gain
I believe it is the difference in Dtf between consecutive position reports.

Re: YB Tracking Gain
Hi Duncan,
If you are referring to Expedition Race tracking based on YB position reports it is my understanding that "Gain" (which can have a negative value to indicate a "Loss") indicates the delta in DMG since the last Race tracking that was compiled by Expedition. I am not sure that if boat handicaps are entered that "Gain" will not indicate the delta in CorrDMG instead of DMG.
To expand a bit; YB does not provide any calculated info along those lines. YB just provides a boat identifier, position, and time in a text file. Expedition massages all of that to develop the information in the Race tracking module.
Hope this helps.

Re: YB Tracking Gain
Yes, Joe is correct.
Gain is the difference in DMG to the reference boat DMG. Without checking, I think it isn't the corrected DMG.
The only association with YB is that YB can be a source of data to race tracking.

Re: YB Tracking Gain
Thanks gents
Really obvious when explained, Look at DMG column and do the mental arithmetic between the ref boat and any other. Thanks.
