This is a bit off topic, but since
@Ultralight brought it up and it was his thread to start with . . .
Honestly, if you want that feature, you might find the Huben K1 to be your best shot at it. It is purely mechanical, but the power wheel does an amazingly repeatable switch in power, and again - it is very repeatable. My .22 K1 regulator is set at about 110 bar, and I have in "nominally" to shoot 18.1 grain pellets ~910 fps, and I position the power wheel with a sharpie mark at 12:00 when looking at it with the muzzle pointed up (the wheel can be positioned however you want it, and then tighten the screw locks it down to the wheel with the detents in it). From there a few clicks counter clockwise (to about 9:00) will raise it to about 970 fps. If I go counter clockwise around to 9:00 again (so 3/4 of a turn from the "nominal"position) it will shoot at about 490 FPS, and it can go lower than that if wanted. The amazing thing is that the speed is very repeatable at any given wheel setting, regardless of where it was set before then.
I was so amazed by this that I ran a unique test a few years back - I loaded up an alternating stack of three different pellets - JSB 25.4s, 18.1s, and 15.9 Hades that all shoot well in the gun. I shot the Monsters at ~42 FPE, the 19.1s at ~32 FPE and the Hedes at ~22 FPE, alternating between three targets in that order, adjusting the power wheel for each shot, verifying speed over the chrony, with each pellet weight going to its own target. The result? Three very good tight groups of five, admittedly at different POIs, and all shot in an acceptable velocity spread for each pellet weight.
I don't have the scope you refer to, but I am familiar with them and they would work great with this gun. As it is for mine, I only load up 18.1s now but I do vary the power as needed and have learned the hold over adjustments needed for the lower power situations I shoot in.
I'm not taking anything away from the Daystates here on this, but for this one "trick" I think the Huben just possibly can't be beat - the ability to shift power by a full order of magnitude with no "normalizing shots" in between is incredible. OF course one has to put the work in before hand to know what the results will be, but once known they are repeatable.
I also have a Sidewinder but I find the power wheel in it is a lot more vague than the Huben, which has solid repeatable clicks . . .
