![]() ![]() I am one of the people where it’s a neat toy but it doesn’t really match up and work for me. Like, at least for things like Xert and FRC in WKO, the amount by which you are above FTP or TP or whatever they call it affects the speed at which that bucket drains, and if their assumptions match up to what you’re really like, it should work, right? I think it would work for some people if their physiology matches the way that W’ degrades in the model. You would really need W’, W’’, W’’’ and W’’’’ if you think there are 4 thresholds, as 4DP assumes. I think a model only using one value goes against the 4DP principle. It’s a wonderfully simple or gloriously complex topic depending on your leaning. Sorry, I said I’d leave the elaboration to the coaches. So: recovery intervals are your friend… they allow you to do more hard intervals! Suffer hard, recovery easy, and you can be way more than your W’. The more you back off, the quicker it refills (some models may have a constant drip of refill regardless of what you’re doing, others add a delay, more complexities apply). But if you back off for a bit, drop below CP, then the bucket starts to refill. The harder you ride, the quicker the bucket empties. If you just head out and ride for as long as you can above “CP” then, by the model, the bucket will be empty, W’bal = 0, at the point you can ride no more (although complexities apply, as always). Everybody has a different sized bucket, those strong for AC generally have bigger ones. The size of your bucket is the W’, the current level of the bucket is W’bal (these are the Skiba names, other names are available). CP may or may not be related to FTP depending on many a multi-dimensional thing. Simplistically W’ is about work above “critical power”, CP. I can easily turn on something very similar to W’ analysis for your GSL rides Sir (although maybe not properly tuned to your leak). Is W’ a considerable KPI in the SUF’s 4DP approach?.Do you consider the W’ when creating a workout?.Is W’ a value a cyclist should consider when pacing an event or a workout?.That’s why I wanted to reach out to the coaches here on the forum to give us more insight into W’. And I can see that Nine Hammers almost does the same. If I look at my training analysis data in Golden Cheetah I can see how “Full Frontal” and “Half Monty” deplete my battery completely. On the other hand, if you’re using a dim light the whole time, you might end up coming home with the battery still half full. If you use your headlamp as a flashlight, it will be very, very bright for a short time, but the battery will also die quickly the longer the light stays on overall. As far as I understand, W' this value tells you how many matches you can burn. If I’m not mistaken completely, the W' value should help predict if and when you will fail in a workout. The other workouts may make you struggle but make you faster in the long term.Īnyway, I wanted to start a discussion about I think the only workout designed to make you fail is “Half Monty” since this test protocol drives its insights from the point where you fail to keep up a certain power. Not sure if, in the end, it really matters to have FTP used with Coggan metrics or not.Every now and then, someone in this forum raises the question of a certain workout is designed to make you fail sooner or later. If you do that, the 'Coggan' metrics will use FTP and not CP to calculate. In GC we compute TSS and BikeScore using your 'CP' value, but from v3.3 you can maintain separate values for CP and FTP in the athlete power zones settings. And if so, do you then want to force any metrics/display to use FTP over CP? Golden Cheeta say says: So I'm wondering if it would be better to set FTP. Not sure if that's outdated at all?Īlso, do you bother making a distinction between CP and FTP? I've just been setting my athlete CP to my FTP since CP is what is used for the power zones, but from what I've read CP is technically different from FTP. I gave it a quick skim/search just now, and it didn't answer something I've found confusing in Golden Cheetah - how do I get it to display TSS in my activity metrics? I think the TriScore is basically TSS (It's "BikeScore", and I don't run/swim so no RunScore/SwimScore included), but I've seen other people have TSS and TSS per Hour in their metrics, and that is what I want.īut it doesn't seem to work. Thanks for posting - will read in detail later.
