From f4cc76d96f411b1ab1a2809379839f5573236f79 Mon Sep 17 00:00:00 2001 From: Peter Hutterer Date: Wed, 7 Jan 2015 13:39:55 +1000 Subject: [PATCH] tools: note that the mouse frequency measured is the highest frequency Some devices scale the frequency based on the input and will provide recordings with different frequencies each time. Recommend to measure multiple times since we can only know what the highest frequency is.
