Execution times - onUpdate - what are the limits for a responsive watchface

I can see a small delay on my Fenix 6X if I want to start an app or if I start showing my widgets. I wonder what are good values (for a complex watchface) that are acceptable.

My watchface can show up to 14 different datas at once and allows a lot of customisation.

Any hints / comparison values that show me what a complex watchface's onUpdate execution time should or can be?

My execution time is between 80-100ms for a very complex layout showing all data at once.

The best way to check this is download similar WFs from the store and see how they look. Use ones that have been around for a while, show about the same amount of data, and have a higher number of downloads.

Will try this. It's hard to compare with my watchface though because I do load fonts and unload them a lot during the onUpdate because I do use rotated fonts to draw data in a circular style.. But thanks for the idea
