Hi - what does WKO have that GC (in version 3 flavour) doesnt?
I used training peaks for a while via a coach, and much preferred GC, but have never tried WKO. I've always assumed that GC has the same or greater functionality than WKO, but that WKO may be a little more polished. (Just to be clear I'm a massive fan of GC - I think its fabulous what the guys have have put together and offer for free!)
Use average power to pace intervals and both AP and NP to analyze ride files. The disparities between them can indicate the variability index of your intervals and course, which can be useful for many, many things.
I understand the use of np & xp feeding into performance manager, but what do you mean by "many many things"? In general I know whether a ride was highly variable or constant when I do it, I dont need a VI or a comparison of np/xp to ap to tell me, and I know that a crit will have a higher xp/np to ap ratio than a time trial, again I dont need a number at the end to know. I find that looking at the power trace in ride details gives me much more useful information than the xp/np value. I want to know the where and why
I had peaks and troughs in a TT, and how long, how many and how large
my peaks and troughs were in the crit; information that I can use to either alter my tactics/approach to an event or feed into my training.
NP/XP doesnt give any of that rich data, so usually I give it a cursory glance to make sure that it accords with what I think it should (as much a check on the data quality as anything else) - and then if the ride is worthy of analysis its straight into the detail.
I'm open to learning stuff about this though, if there are other aspects worth considering that I missing.
