Just a follow up to point out a use of the new % differential (or gap) format of showing VDC% on the Segments and Primary screens (i.e. how much each VDC value differs from the best value).

In the above screen shot (DMR 8/7 R5), the 2nd ranked VDC differs from the 1st ranked by 2.9% (let's call it a gap of 2.9). In your opening screenshot in this thread (DMR 8/6 R1) the difference between 1st and 2nd VDC is only 0.1% (call it a gap of 0.1). Although there is a clearly ranked 2nd VDC horse in each race, the 2nd ranked VDC horse with 0.1 gap is clearly closer to the best than the 2nd VDC horse with a gap 0f 2.9 And in the first race above, the Top 2 VDC are much closer to each other (practically tied) than they are to the next 2 VDC with a gap between the 2nd and the 3rd horse of 2.2.

While surely not always significant, I would not be surprised if, long-term, those VDC #2s with smaller gaps outfinished VDC #2s with higher gaps. And VDC #3s, etc, etc
