-# Cherry MX-style switches and diodes are not susceptible to noise, no need for noise-resistant algorithms.
-# This significantly reduces latency.

-# The matrix scan frequency seems to be around 1820 Hz, so even sym_defer_g would perform ok,
-# but the "defer" part would mean we would wait DEBOUNCE ms before sending any events.
-# Using "asym_eager_defer_pk" does not seem to benefit us in anything.
-# The GMMK Pro has more then enough system resources for a per-key algorithm.
-# Using an "eager" algorithm leads to extremely low latency while also reducing the chances of chattering
-# due to it's "post-event" debouncing (of sorts).
-#
-# I have observed zero chattering or double-keypress issues on my Gateron Yellow switches.
-# Most chattering issues on the GMMK Pro seem to be related to its proprietary hot-swap sockets anyway.
