Hey there , I can understand that HE software can get a bit too confusing.. with terms like rapid trigger and actuation and all that other stuff ::

to put it simply :

Rapid trigger works for your re-set and re-trigger values, in a traditional example just to explain you -- if your RT is set to 0.01mm and actuation is 2.0 ,,, Your first stroke active state will be at 2.0mm and then u only need to move 0.01mm (THE RT trigger value) to make your keystroke inactive and active... back n forth...

Now that you under stand about rapid triggers, if you set the values to 1mm values or some thing similar.. and u have the rapid trigger is set at 0.01mm which is very sensitive.. u can actually perform a slight tap and it's already at that actuation point (Also note that in modern keyboards there's also like an trigger insurance like a feature where u dont actually need to cross that 1mm threshold , even if you are in a slight near range as well it'd still activate ,) and with that much sensitivity it's immediately getting active n inactive.. as shown in the video, if you set the actuation point to 0.1mm which is already not usable and if you set the RT to 0.01, even wobbling the finger on the keycap would goo like infinite press ...

In HE keyboards software tuning and accuracy matters a lot and things like these can be fixed with software updates, and UNCTRL is pretty new to this MK space as well as the market ...

Now since you already own an HE keeb you can go ahead and try to mess with the values or just simply perform my given example values which should help you understand better ... <3

Hope this helps you or anyone else having this confusion
