Understanding athlete levels

I’ve just finished a workout, and could do with some help understanding athlete levels:

I assume the green numbers mean this workout took those levels up, but what are the numbers before and after the “/” and why are they sometimes different to each other?

Does it mean I did 5.5 out of 5.5 for Endurance, but only 6.8/7.0 for tempo? And 7.0/7.2 for sweet spot? Why would that be? I was in ERG mode the whole time (i did ease off the pedals in the z1 gaps, but the workout text often says to back pedal etc in those if needed).

Yes.

Although workout text sometimes says it’s ok to backpedal, you will still get a lowered score if you perform less work than prerscribed. It should also be mentioned that those instructions are from the old TR and should probably be disregarded. Also, there is a reason that a workout like this has higher % of FTP during rest intervals, so in this instance it’s probably even less of a good idea to backpedal.

Ok, so a brief cessation of pedalling, or a quick pause of zwift workout to adjust the fan in z1, would drop those scores?

Yes, that is probably what you’re seeing.

You can see it on the chart itself. Those drops in power.

I’m surprised that split second pauses can have such an impact… but it is what it is.

It looks like they are 30ish second micro breaks in the last work set. But hard to tell here.

Do you mean the two drops i’ve marked by a red dash:

It looks like you were a watt short of the target for the final two intervals. :melting_face:

I’m not sure if that’s worthy of losing 0.2, but I’ll ask the team what they think..

I was in ERG the whole time, so I had assumed I would be “forced” to keep within an acceptable wattage range! 226w is 99.6% of the 227w target for instance, surely that is good enough?

I think this could be at least in part from ERG performance in Zwift. The only time I’ve ever seen this before was with a Zwift workout. :thinking:

It would be good to know how close output watts need to be to target watts in order to achieve “full marks”, and whether zwift ERG is adequate in that respect. I do feel that being 1w out is acceptable, especially as there is no way people not using ERG could maintain that.

So, after a closer look, I think part of the reasoning for your scoring is likely due to that third interval being right at the bottom edge of your sweet spot zone. This means any fluctuations in power, even with ERG, could record data in your tempo zone.

Sometimes these types of fluctuations can affect your overall workout score, particularly when intervals fall at the edge of a zone, like in this case, but TR AI doesn’t actually use these levels for much, and in cases like this one, where the workout was executed nicely, the athlete’s training won’t be impacted whatsoever.

It’s frustrating to see anything other than a perfect score when you knocked the workout out without issues, but keep in mind that we’re looking at your power, not the workout score in the end.

This is an edge-case issue that we’re aware of, and I’ve reported this case to the team.

Let me know if this helps and if you have other questions. :slightly_smiling_face:

That makes sense from a software point of view, but should definitely be rectified in future updates.

I remember on a recent podcast, Hannah reminded us that “the zones are all arbitrary, and as you move between them the various biological processes gradually reduce/increase” (I paraphrase, but basically there is no sudden difference between each zone).

So based on that if TR wants me to pedal at 225w it shouldn’t matter which zone it’s in. The athlete levels, and progression within them are a key metric and motivator. I scan my calendar and see the workouts that will bump up my levels. They’re my “events” (in the absence of races etc). So being penalised for being just inside z3 not Z4 etc is actually quite demotivating.

Thanks for looking into it though.

Yeah, I agree with you.

I know that our athletes pay attention to their levels, even if they aren’t as relevant in terms of their training as before, so I’d like to see this fixed as well.

Keep up the good work, though, and don’t let that arbitrary 0.2 get you down!

Ha… I won’t worry too much :sweat_smile:
