Tss form etc vs TP

Hi I have used training peaks a lot in the past and am considering transferring my training plans to intervals as I like the software. I’ve noticed tss, etc is different in the platforms. Eg today I’m at 46 fitness in training peaks

Fitness, here, is calculated using today’s values, whereas TP will use yesterday’s values.

Once you have your history imported, the trend will be the same.

TSS is called load and should be the same.

Thanks

Would that explain such a big difference in the numbers?!

The numbers are the same for me.
Assume you have your FTP set the same in both platforms?

What would define as a big difference?

You can set your FTP retrospectively, so that it ties up with TP. Then refresh the data to bring everything inline.

I looked at my data for 22/02/2023 and today because of the difference in the calculation of fitness and fatigue:
Intervals vs WKO5

I’ll look into the ftp settings. Over 10% difference from a function which looks at 42 days doesn’t make sense that it is caused due to the one day difference in calculations time, so I’d say it’s without doubt a big difference which I quoted!

Thanks for the help
