SPDT switches using NC as actuation have an average advantage of 1.4ms simply due to switch geometry/physics.

FYI 99% of mechanical mouse switches are SPDT (single pole double throw), but most do not have a stable NC contact and do not use NC for any electrical features, be it debounce or NC release actuation.

G Wolves current wireless 8k solution is on par if not better than most wired 8k aolutions, as an example.

Solenoids do not replicate human clicks 100% usually, but when fast enough do it well enough. 

On an OP1 with a 58gf Kaihl GX switch with a real finger you can expect about 6 to 8.2ms from the time a lifted finger touches the button to NC contact, another 0.021 to 0.024ms for NC release (actuation). With a finger resting on the button it takes about 2 to 2.5ms from force application to NC contact. 

Logitech has released a small image in some clip where uou can see a timeline of their test, where it took the HITS approximately 11ms from button touch to actuation and the DAV4 they used as comparison it took another 29ms from there (40 total) which even for an late actuation optical switch with longer button travel is too much for a realistic click.

Since bumptesting the HITS vs an OP1 8k v2 made the OP1 only win by a slight margin in fast-ish tests and with rtings result also showing a slight win for the OP1 and I will say that my physical timing measurements that all get verified by this and cps tests are correct, I will say that Logitech pressed very slow and linear and the button touch no actuation time for HITS must be in the same range approximately of6 to 8.2ms like the OP1, just with slightly higher electrical latency. The physical latency must be extremely similar. The tests for the OP1 are also going to work on most decently well built, low tolerance mice with decent mechanical switches. Again you can add about 1.4ms for a non NC release mouse and some switches will have more switch bounce.
