With DCS, my personal recommendation would be similar to what I outlined above — have most of the settings be uncapped, a bit like the attached screenshot.
Then use a combination of your hardware gain knob and the TelemFFB app to customize for an aircraft until it feels right. If it’s too strong, turn things down, if you don’t like certain effects, turn them off. The nice thing with TelemFFB is that your customizations are aircraft specific, so once set, it will just detect the aircraft and bring up your saved settings.
As was said earlier, settings can be highly contingent in what sort of extension you have, the weight of your grip, and also personal preference, do you like a stiff or looser spring force, etc
There are multiple holes, but usually you only need one screw, because there is only one flat face on the shaft.
