If you cannot spotmeter well the night scene then we have a solution (modern times): use a DSLR and make several test shots (or your smartphone with special apps), when you have the right exposure for the DSLR you only have to apply LIRF correction.
Beware, each area in the scene may have different LIRF, shadows have more LIRF than highlights, for an ideal night metering you should meter diferent areas independently.
Ideally, from LIRF film calibration, you may be able to precisely predict density the "on negative" density you are to obtain for each spot.
Full moon lits from 0.05 to 0.3 Lux on your subjects, not much.

I have used Tmax and have Acros (not experimenting with that though, saving it). Next time will try Tmax. And plan to spend all night there. Of course can't get back for a moon light scene till July. Partial shoulder replacement 16 June.

Acros the right stuff for the night, regarding LIRF
Another approach is this one: https://en.wikipedia.org/wiki/Photog...rsensitization

Shoulder replacement mid June - probably unrealistic to think about July. Knees and shoulders are hard. I had a knee done - took a long time. One of the guys at PT had had his shoulder done and he seemed to be having it worse than me. Hips? Not so much. Good luck

With such long exposures, T-Max 100 is stops faster than Tri-X because pf reciprocity.

Another answer which doesn't require a digital "camera". Meter important highlights and place on Zone VII or VIII. Let the shadows fall where they may. The result wil look like a night shot.

Yes... I agree. This is a very good recipe.
Anyway if we want some shadows recorded then we have to refine our metering-processing, because when recording those shadows we may blow highlights.
Re: Moon lit scene with Txp 320
How about the lunar 11 or looney11 rule which states:-
Let us start with the basics. The moon is very bright in relation to the rest of the night landscape. How many times have you tried to photograph the moon only to find that the result is a bright white blob in the sky. If our only concern is to capture the detail in the surface of the moon there is a simple rule to follow to achieve the correct exposure. The rule, called the “lunar 11” or sometimes “looney 11” rule, is a formula to obtain the correct exposure and capture the detail in the moon’s surface. Start with your camera in the “manual” mode and make the following settings:
•Aperture (f/stop) – f/11
•ISO – 100
•Shutter speed 1/100th second
Under ideal conditions these setting will get you very close to the correct exposure. Adjustments may need to be made to compensate for atmospheric conditions, phase of the moon and light pollution. If the moon appears too bright increase the shutter speed or conversely if the moon appears too dark use a longer shutter speed or open the aperture. If you use a longer shutter speed, be aware that the moon and earth are moving. For a telephoto lens never use a shutter speed slower than 1/30sec. or the moon will be blurred by the movement.

Re: Moon lit scene with Txp 320
That rule is for taking photos of the bright disk of the moon, not the landscape under moonlight. That exposure will result in a blank negative shooting a landscape illuminated by the moon.
Re: Moon lit scene with Txp 320
From my M9, 25mm, f4, ISO 400, 32 sec under a harvest moon. And that equals the general Full Moon Rule for Acros at f8 for 8 min.
