Sound right?
Indeed, another consideration is that ASIAIR calculates the meridian position using the model-adjusted clock, whereas Gemini-2 gauges the limit's midpoint via the spirit level's state. Maintaining minor model time adjustments in Right Ascension (RA) helps keep the Limit points precise. As the Go-To Slew must occur reliably within the WGL.? Narrowly setting limit points requires an accurate level state. And the mechanics of long OTAs don’t allow wide settings.?

An example I use for a long refractor:
Gemini-2 Limits;? East 93:00, West 93:00, WGL 5:00
ASIAIR MF;? Before Meridian 0, After Meridian 0

For a C11 I could use a slightly more forgiving set:
Gemini-2 Limits;? East 98:00, West 95:00, WGL 8:00
ASIAIR MF;? Before Meridian 0, After Meridian 0

These favor a small exposure outage during flip routine.

Yours depends on the Optical Tube Assembly (OTA) in use, the tolerable delays during the meridian flip, and the number of acceptable Go-To retries following plate verification.
