Power indoor vs outdoor

Hi all, I notice it is harder to keep target watts indoor than outdoor.

I read this article Indoor vs. Outdoor Training: What is the difference | Alpecin Cycling

where they mention that power targets indoor should be 10 to 30w less “Nevertheless, athletes should adapt their training intensity to indoor training. Depending on how well these tips can be implemented, power should be 10 to 30 watts lower than outdoors.”

Anyone agree or not with this?

In my testing I find this to be true.

In my case it’s ~4% delta.

Thats why I test when I start my indoor season and again when its decent enough to test outdoors.

Your wattage may vary
