Yeah, I routinely see L23 airspeed errors of -20 kts or more in a full
slip. I emphasize noting the pitch attitude before entering the slip and
maintaining it in the slip. Ignore the ASI.

Any pot pitot is going to be inaccurate, a 50 deg slip as discussed earlier
means you can only rely on attitude for airspeed.
On my Cirrus anything more than a very modest yaw results in wild airspeed
fluctuations - presumably due to buffeting of the static and the disturbed
airflow over the pot.

One reason why people are suggesting you need extremely good airspeed control
and a little extra speed in case of misjudgement.
