Misconfigured crank length and power

Hi all,
I dont know why, I had all my activity (around 4-5 years) with a misconfigured crank length in the Favero Assioma app (it was 172,5 and my crank length is 175).
What should I expect, now that I configured it correctly?
I mean: will the power read a little higher or lower (let’s say that I can perform two workouts identically)?
I imagine the difference will be quite low, but maybe when in the red zone I could go in a red-er zone if the new reading is lower…

thanks in advance, have a nice ride!

This reply seems to contain the answer I was looking for.
As I lied in the opposite side to the powermeter I should get higher power reading for the same effort.
I should, in any case, double check the settings in TrainerRoad and Garmin configuration, as apparently this is the real value used by Assioma (therefore, why they put the field in their app?)

The value you put in the app is the one it uses - until it gets an override from Garmin etc… So it does have a use, but it doesn’t push that value and instead accepts overrides externally. For me, my summer bike is 172.5, winter/turbo is 170. So during the Winter, Garmin is set to 170mm and used only outdoors and when I go outside or come inside, the settings align. In the summer, my Garmin is set to 172.5 for my summer bike and I have to use the Assioma app to reset to 170 for turbo sessions. Not every indoor use will have an associated app. My frustration is the other way - why should Garmin continue to override the input device, when the input device has been set directly?
