Interesting…but I think using CP may still be a few steps short of 4DP. I imagine that, like FTP, people with similar CP may have widely varying power at NM, AC and MAP. So training to a set percentage of CP would be like training at a set percentage of FTP and come with the same shortfalls.
That is, unless the multiple tests used to determine CP are similar to those in 4DP and any individual training plans created take those different aspects into consideration.
For my money (and outstanding value) imma stick with SUF/SYSTM.

@Glen.Coutts was just thinking another metric to play with. Wondering if there are any specific workouts in the library that would replicate the CP testing the doc references in the article…

I think you should do them all and report back on your findings

Anyone recognize this workout? 
14VG, DAYT, Shovel, Omnium, Tool Shed all come to mind. Kitchen Sink maybe, if you’re demented?

I’m just an impresario at heart - I like shiny things. So the CP metric interests me. I’m fully invested in 4DP nonetheless. Even if I hate it.

I’m hoping a SUF scientist weighs in.
Ok, so I’ve just looked up my best 3min and best 12min power according to intervals.icu. Calculated the CP, and then googled the power zones to train for:

Now the upper limit of the threshold is close enough to my 4DP FTP, but the VO2 max should be about 140% of CP to match my 4DP MAP. I won’t be suffering with these numbers…
It sort of proves that my rider type weakness is the sustained effort, but it also shows that 4DP numbers are much more effective for my rider type.
