FactoryTD 1HD-FTE: HDJ78/79 with H150F gearbox:
1st: 4.529
Transfer: 2.488
Diffs: 4.100
Landcruiser first gear reduction = 46.199
Patrol auto for chubba
Diff 3.9
1st gear 2.784
Transfer stock (2.02) 3.9 x 2.784 x 2.02 = 21.93
Transfer 43 (2.86) 3.9 x 2.784 x 2.86 = 31.05
Transfer 63 (3.29) 3.9 x 2.784 x 3.29 = 35.72
Transfer 85 (3.743) 3.9 x 2.784 x 3.743 = 40.64
that last number is obviously the number of engine revolutions required to turn the tyre once
very hard to compare a manual to an auto, but on paper thats what it is. depending on which landcruiser it is.
May be worth checking, as I am not sure how much the landcruiser varies from ute to other models.
What landcruiser are you trying to match to?

A343 1st gear 2.804:1 which is the 95-97 auto
Transfer low 2.49:1
The 442 1st gear is 2.950:1
SO,
and landcruiser auto, to compare to your auto, assuming 3.9 diff gears
for the A343: 27.23
for the 442: 28.64
so, which landcruiser and what gearbox are you trying to match?
Obviously bear in mind the torque converter multiplication too.

So I am spamming my own thread here
for the landcruiser a small googling tells me The torque convertor is a 1.8 to one multiplyer.
so that would put the actual reduction to the wheel at
27.23*1.8=49.01
28.64*1.8 =51.55
which is pretty bloody close to the manual reduction, so I reckon they may be right.
I could find no detail, in the workshop manual or on google about the nissan auto torque convertor reduction, but the auto will fit in a 300zx lol
even if we assume a similar 1.8 ratio in the pootrol
using the 63% with the 3.9 and auto first gear the ratio was 35.72 multiply that by 1.8 = 64.30. which is pretty close to a manual with 85%. but obviously the converter gives you much more room to move. I really dont know what the patrol torque convertor ratio is though.
I dont think I have posted it here yet either, 4.11 ratios
Patrol late model first gear reduction = 35.384 engine revolution to one wheel revolution
Patrol late model first gear reduction 24% = 43.406 engine revolution to one wheel revolution
Patrol late model first gear reduction 43% = 49.976 engine revolution to one wheel revolution
Patrol late model first gear reduction 63% = 57.49 engine revolution to one wheel revolution
Patrol late model first gear reduction 85% = 65.406 engine revolution to one wheel revolution

Very interested to see how everyone goes with this. Unfortunately I don't have the coin at the moment, but it has been on my mind ever since doing the Maytown Track and needing some crawler capacity in a general tourer setup. I had the 43% reduction in mind, but I think you might be spot on here with a 63% reduction being the best all rounder.
Between Patrols ATM. Had a beaut GU with 6.5 Chev TD. Next is a GU ute with a 4.5 litre Cummins conversion and a camper on the back.

Sounds good but I'd go with 85% if I'm reducing.

It is all horses for courses really, depends if you want crawl only, or some capability to still move between things without coming out of low range
