Energy impact on app switch

Describe the bug
Hi, I'm a new user of better touch tools which is really a very great app

I was looking a the energy impact of the app when I noticed something weird, that might fixed.
When switch app, the energy impact significantly increase (chose option to refresh every second to see). I would understand that it's checking if I have particular settings for the focused app, but I only use global settings.
Expected: constant energy impact
(I have a low energy impact (between 0 and 2) when working, but the average is 30+. When switching app, it raises to 5 - 10)

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Touch Bar
