As for 2.4x vs 2.5x and 4.0x vs. 4.1x. It turned out that some units
measure velocity in 1000Bps, other - in 1024Bps. In order to make speed
control code more stable 1x was redefined as 1352 instead of 1385 in
5.17, which is why you might observe slightly varying factors. It's
nothing to worry about. A.
