I’m contemplating my subscription, do I sign for another year with Xert. I love the magic buckets and new AI training which gives you target interval watts to incorporate into your rides.
The one issue I have with Xert, the reason I keep leaving. Is that Xert always estimates my TP ~5% higher than any other platform/system…. The breakthroughs are recognised at the right time, I love MPA, but the TP is always ~5% higher than I think is correct. Example, from a race today, other platforms raised my FTP to 241, whereas Xert raised my TP to 252
Is there anyway to scale the TP calculation, so that Xert always calculates it to 95%, or some setting that would acheive the same…. I know this sounds crazy, but it would make Xert much more useful to me if I could align/control the TP calculation scaling.
Why do you want to do that? If Xert’s signature represents your performance ability well across the parts of the curve you care about and e.g. gives you challenging but achievable workouts / intervals above TP, then does it matter? I partly say that since if you lower TP you will need to raise HIE and maybe PP (so that you still have a BT at the right time) and it may mess up other parts of the curve you care about…
I’ve used Xert on and off for many years. I have always found that it over estimates my ability, maybe because I’m in my 50s, unsure.
I want Xert to do what it does, but just know when estimating TP, suggesting workouts, etc. that I’m 95% of what it thinks I am.
Otherwise I’m always manually guessing my FTP setting (deducting 5%) for my other platforms to do workouts.
On the challenging, but acheivable…. perhaps they are, perhaps it’s me that’s getting lazy in my old age. But the Xert TP is too high for me to use for most high intensity workouts (at the effort I’m willing to push), hence I use my FTP pulled from other platforms.
Sounds like your signature is not quite right, and also like you’re not using Xert workouts above TP for that reason. That’s a shame since above TP is where Xert is better than any other platform. Your approach of using %FTP workouts is missing out, but I can see why you are doing it.
It should be fixable though. Without knowing anything about you or your signature it’s tough, but my first guess is that your PP and HIE are too low - do you have breakthroughs from sprints? And from other very short efforts?
You can try manually fudging it in your last BT activity e.g. lower TP by a bit and increase HIE by a bit (maybe also PP if it’s low) so it’s still creating a BT (MPA just touching power), then save / lock.
From that screenshot it looks like PP is low relative to TP at around 650w - is that your true max? If you are injured, or only sprinting indoors, or you just don’t do max sprints, it’s likely understated so you may want to increase both PP and HIE and lower TP accordingly… best is to do some all out sprints outdoors, when fresh and warmed up, though
Interesting, seems I need to do some reading about how PP affects TP and vice versa. Most of my harder efforts are during zwift racing, or short hills outdoors, so 1-8 minute effort, rare that I do max sprints - I expect my max sprint to be nearer 750w minimum
I just added 100 w to my PP, and it brought my TP down by 2%. Or thereabouts. If I can add more watts through an outdoor Sprint, then your theory may be the answer to my problem.
