Zwiftpower is basically what’s ‘right’ and wrong in racing in that context.
A mate did the Watopia tour race yesterday in D.
The first 10 riders over the line finished on over 4w/kg in D… one was close to 6w/kg.
Zwiftpower filters them all out of the ‘results’
It also has leagues, rankings, points etc.
Anyone finishing outside of Cat limits are either kicked out, or moved up etc. People without HRMs can’t be on the podium and people without smart turbos cannot either.
It’s basically what’s the ‘fair’ representation of the results after the rules are applied.
