Help understanding w/kg in a race (Event ID 2771206)

Hi Dean, thanks for the reply. This image doesn’t really show the full story as I know it’s a snapshot, but my w/kg was 4.5+ ish the whole race (I’m J.Sanderson (Buxton CC)), as was one other A grade you can see in the group with me, but we were hugely dropped by/racing/hanging on with guys with B beside their name, and whose w/kg never rose above 4. Even on the climb, when I was hitting 5.5+ I couldn’t drop these guys who were doing 3. I’m no expert but assumed that w/kg was a big factor esp on climbs.

The event ID is 4644529 (I think!).
