Form (TSB) as of yesterday or today's?

Feature Requests
1

Hi,

I don’t know which concept is the right one but Golden Cheetah’s description of Form (TSB) seams to be more logical at least for me: “Training Stress Balance/Stress Balance. It’s the result of subtracting yesterday’s Acute Training Load/Short Term Stress (“fatigue”) from yesterday’s Chronic Training Load/Long Term Stress (“fitness”)”

Either or is there a way to set Form as the day before value?

Thank you,

There isn’t an option to switch to yesterday’s data but I do have that on the todo list.

@david According below sources form should be computed on yesterday ctl & yesterday atl:

(This is TSB details from the Joe Friel article you are referencing on the fitness feature itself)

I’m the guy who run Elevate (for strava & desktop app), I also implemented it as is.

Having it as an option could be great.

By the way, amazing work on intervals.icu :wink: !

Thanks :slight_smile: When I started Intervals.icu it just seemed to be the right way to do it. Since then I have seen Elevate and GC and others that do it using yesterdays data. Hopefully I can get an option to switch implemented soon. Very busy with a bunch of much needed running related stuff right now.

@david Any ETA for this? Should be a “quick win” no?!

Thanks again,

Thomas

Unfortunately not :frowning: Intervals.icu mostly just stores CTL and ATL and calculates form when needed. So using yesterdays numbers for form today is a complication because yesterday’s data might not be easily accessible.

Ok understood. Will you work on it by the way?

Yes I will definitely sort it out (eventually). I am sure you know all about an endless todo list!

Hiya @David any update on this?

+1, would really like to see this. I’m using intervals.icu for most of my planning and analysis but have built my own little dashboard just for this.

Hello,
I have been using Training Peaks for 5 years, and I started using Intervals.icu in the fall last year. I have all of my workouts uploaded since then in both apps. What I noticed that there is a discrepancy how Form (TSB) is displayed between the two apps. For example, my yesterday’s Fitness CTL was 41 and my yesterday’s Fatigue ATL was 73. And since the today’s Form equals yesterday’s CTL - yesterday’s ATL, my today’s form should be -32. This is the number TrainingPeaks shows, but today Interval.icu shows Form to be -23, which seems to be tomorrow’s Form - my today’s CTL - ATL, which are 40 and 63 in both apps. It is quite a difference, because -32 means high risk zone and -23 means optimal training zone. Can you please help me out, is there some setting I am missing? Thanks in advance.

should be the same as this

if yes, I’ll move this thread there.

Thanks, it seems to be the same topic really. I saw the thread but it was from a long time ago so I thought the issue was resolved. I enjoy using Intervals.icu and still try to explore some features. I think it offers everything TrainingPeaks offer and vastly more. TSB calculation is a minor quirk in comparison, I just have to remember to use yesterday’s TSB - in my experience this really reflects how fresh I am.

Any update on this? I brought this topic up in a diffrent post because I did not discover this one yet.

Great news. Thanks :slight_smile: It’s feasible to look previous day value but the option would be welcome :slight_smile:
