+# 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.
