Airspeed and altitude HUD display frequency.

It is the airspeed refresh rate ...HUD Sampling
If you study enough HUD videos on Youtube, you'll notice there are small delays in numerical data sampling such as
airspeed and altitude (either caused by HUD or CADC processing and/or the 'natural' delays in pitot-static systems)
and not an instantaneous display of individual numbers. An example is a quick acceleration in airspeed will 'jump'
from value to value...i.e., 102, 105, 109, 113. In DCS  the code  display every single digit
through an acceleration/deceleration or changes in altitude.  reference youtube . https://www.youtube.com/watch?v=BHx-OWdHqf8

Exactly. You can't read real time. Need little bit latency, lag.
