"A long press will power the optic on and off, and momentary presses switch reticle options, i will have exact times when the SCS is released in the May time-frame."
I interpret that as "exact times" refers to how long the "long" press is to turn the optic on or off, and what "momentary" means. Something like, "hold control button >3 seconds to turn optic on or off, momentary press to switch reticle selection", or similar, for example.
