Not referencing racing which has no ride leaders, but rather for general group ride type events. Why is wkg used and not watt range?. Wkg has a dependency on knowing the leader’s weight to gauge relative effort. Just showing watt range would seem more informative. Eg. 1.5-2 wkg (for 60lb ride leader) means 90-120 watts. Which is more informative to be provided – the 1.5-2wkg or the 90-120 watts range?
Of course knowing the ride leaders weight would provide even more insight, but barring having that, wouldn’t wattage mean more to more participants?
