The precision of the timer used for calculating entity speed has been improved. This reduces the "back-and-forth" motion of the crosshair and should result in smoother aiming. I will post the config file I used on Discord. The settings are
Line 92) 25
Line 93) 20
Line 94) 10
Note that these changes invalidate the default settings for aim prediction, so you will need to update your config file.
These changes require Speeder version 193+.
