It worked, thanks!

David, my HR vs Power chart filtered for âVirtual Rowingâ is blank. Previous to a travel break in late September/early October 2023, I categorized my indoor erg rowing workouts as âRowingâ and that data successfully displayed on the graph.
Resuming my erg rowing in late October, data from my now categorized âVirtual Rowingâ workouts do not show on the graph. Any thoughts?
You have âVirtual Rowingâ as a separate sport in /settings. Rather delete the âVirtual Rowingâ sport and add âVirtual Rowingâ to the activity types for âRowingâ:
Then you should be able to see everything together.
I am 100% certain this is me being box as a rock of dumb, but can anyone explain how this works? I canât see how w/hr is relevant without also having time in the equation. Is it for 1 min intervals?
These are âcleaned upâ chunks of 30sec where you plot the relation between heartrate and power.
If the plot moves further down right for different dat ranges, it means that you are fitter because you produce more power for a given % of LTHR (or maxHR).
Itâs a nice feature where you can clearly see that there is a linear relationship for power to HR when within the aerobic range.
Hereâs mine for Running activities over the past three seasons, showing that my running is definitely getting better this season.
Same for outdoor/indoor cycling:

Thnx David for your response. My challenge with doing as you suggest is My erg rower (Ergatta WaterRower) has two different Power meters (S4 & SmartRow) that read Power differently for the same workout. Each allows me to share/compete in workouts with different user groups. My hope was to track my stats separately for each in intervals.icu, which is why I created âVirtual Rowingâ as a separate type. Any thoughts on an alternative solution?
BTW, Iâve run into an issue using âVirtual Rowingâ as a distinct activity when using TrainerRoadâŚ.my planned âVirtual Rowingâ workouts do not download into my TR WOD. Alex is working on a solution to that issueâŚ
What do you use to measure your running power - Garmin watch I presume?

Tx for answering this. The chunks are actually 1 minute long and there is quite a bit of processing to get rid of âbadâ ones (e.g. cadence much lower or higher than normal, any stops etc.) so only clean âyou were riding/running for the whole 1 minute at normal cadenceâ stuff is kept. And HR lag is adjusted for.

Unfortunately my curves are also all over the place. My heart rate monitor disconnected very often in the past ( due to bad wifi connection with Zwift and Companion App). I donât think that it would be possible to find out all of these activities and remove them manually.
Wouldnât it make sense to just ignore the files where heart rate data has too many zeros and donât use these rides for the graph? Thanks for the great work.
Iâd love the forumâs help in interpreting my data. I assume this means that Iâve improved my aerobic fitness over the past several years, especially this year, when I did a nice extended base season of Z2 work. But once you get above my threshold, which is currently 265, the lines come together, which I assume means my high end fitness is similar, but not better, to yearâs past.
What do I take from this? That as I sprinkle in high intensity, now that weâre getting into summer, Iâll be able to move the whole line to the right, which would signify measurable progress?

can anyone help w/ the explanation of the Legend?
like in the pic above it shows
270w 157bpm 69rpm 19m
what does 19m represent? 19mins? Total time that this data is based on?
tx
Pretty sure itâs 19m at those exacts watts

Nasatt is correct. That means there was 19 minutes of data for that point. It gives you an idea of how reliable it might be.

@david currently, when selecting a season, the date range (e.g., Oct 31, 2022 - Oct 29, 2023) is shown. Would it be possible to display a badge with the season name instead (e.g., Season 2022/23), similar to how year selections work?
Also, have you considered adding tabs or a similar feature? With so many charts, performance is starting to lag, and switching between athlete comparisons and time periods for a single athlete could be more streamlined with tabs.
Thanks for the great work!
