So who is right? You in February or you now? I'm seriously confused.
I think what you are getting confused about is the difference between default program settings and the default behavior of how the silencer settings automatically change with manual changes to reactivity.
Regarding silencer default behavior, for some crazy, unknown reason, XP decided to program the Deus (independent of preset mode) so that silencer will change to the defaults I described in the table above if you change the reactivity setting from the preset program default without going back in and manually turning silencer off. So while the default setting for Deus fast is reactivity 3 and silencer -1 , if you change the reactivity setting to 2.5 or 4 then silencer will automatically change to the default associated with that reactivity setting (i.e., for reactivity 2.5 that is 2 and for 4 that is 1). Whenever you change reactivity, you have to manually go in and change silencer back to -1, if you want to turn silencer back off. Even if you go back to reactivity 3 (the Deus default) you will have to change silencer from 2 back to -1. This is something every Deus user has to watch out for. This is an undocumented “feature” or quirk with Deus that I only first learned about from the Andy Sabisch Deus handbook, it is not described in the Deus user manual.
Regarding program preset defaults, XP set up Deus Fast, Deep, and a couple other preset programs to have silencer off by default regardless of the the default reactivity setting for the program e.g., 3 and -1 for Deus Fast and 2 and -1 for Deus Deep), but if you change the reactivity setting away from the program preset default, silencer will behave as described in the table above that you quoted.
Regarding ORX, I took XP’s description of the ORX Coin Fast and Coin Deep programs to mean that for Coin Fast, silencer is on for the default reactivity setting (which is different than Deus) but will behave as described in the table above if you change ORX reactivity (which is the same as Deus). For Coin Deep, the silencer feature is off at the default reactivity setting (same as Deus) and remains off for all reactivity settings which is different than how Deus behaves. I suspect that XP did this as a simplified way for the ORX user to have a choice of silencer/no silencer since the silencer setting cannot be manually adjusted by the ORX.
Hey, I didn’t design it, just trying to describe this quirky setup, which is hard to do in words without causing confusion, obviously.
