That’s a pretty blanket statement without actually considering the realities for what impact the new system will have. A ranking system is also not cruiser proof. I could exclusively enter races where my I am the strongest rider but my ranking will not be too adversely affected based on the strength of the field. People do not race enough, with enough variety, for any ranking system to accurately and consistently match for rider strength and ability. It’s completely dependent on the quality of the system, it is certainly not simple. My ZP ranking results have been really low (bad) from racing ZRL A1 all season, yet when I raced B in the FRR I was getting huge ranking results each week is much lower quality fields.
Now you know I support the development of a ranking system, but to suggest that is the only way to stop cruisers is, well, nonsense.
The purpose of the question was to discuss if the CP and MAP system will eradicate cruisers.
eFTP, let alone CP/MAP, as previously discussed would be a great way to do it, because it is not realistic or worthwhile for a rider to manage every effort on zwift to keep power down across all durations so that the system thinks they are weaker than the are, then enter a race in a category lower than they should, to continue keeping power down, to get the glory of a win. Is it possible? I guess it is, because sprint power is not considered in the model, but is it really going to happen?
The one change I would push for is to also include workouts in the calculation, because for anyone also carefully monitoring their power in workouts, well to be honest - they’re a bit weird and we should probably just leave them be.
