Smallest is a 24t normally on the 110 setup (74 inner)
94 four arms, no comment... bearing in mind the section
I think you mean 5 arm 94 - 58/56 Compact/Micro Drive ?
20t on the MicroDrive and I think they also squeezed a 20t on the Compact as well.
Smallest middle ring to double with that would be 33t for a 110 and 29t for a 94

Re:
I'm sure I have 32t middle rings currently on my triple 5 arm cranks
Apols FC , I meant newer four arm 94. I'll do a query for that in the relevant section.
Either way, I mean in the middle, not granny
So, something like 30/44 maybe

You can certainly go to 30 on a compact (94mm bcd) as I have one, but think 29 is possible if you can find one. I was going to do the whole 30/44 thing.

Thought you might have been wanting 36/24 doule, much like modern setups.
Nothing to stop you using the middle ring though and a larger granny, they can be had at 28-30 teeth on 110/74 setup.
For 4 arm do you mean the er modern (end of 90's MC40 STX and afterwards) 104/64 ?
If so it's 32t & 22t normally.

you mean a 'hidden 5th arm' then, so still a 5 arm ;-)
Same rings apply as the 5 visible arm setup
