Default Max number of channels in a 4.2 rig confusion?

Okay, I am about to probably make an idiot out of myself with this one, but for the life of me I can NOT figure out from the knowledge base WHY they list 72 as the max number of channels..

I understand that the standard Disk I/O cards get 8 a piece so that should be 24 IO pairs right?
Then they list an additional 5 Bridge IO cards with 8 a piece there as well so 40 more..
Now that would give a total of 64 pair IO.. Not 72.

They then list 4 Farm cards, which is okay, but still no more inputs right? They are farms..

So where does the magic 8 extra inputs come from?? Some of the Digital IOs or something on the Bridge cards? Or on the interfaces on the Disk I/O cards????

This is nubus with the expansion chassis.

As one last question, am I under the correct assumption that no matter what even with 72 IO's I should only be able to record 24 of them at any given time which is the limitation of the 3 disk IO setup under NUBUS TDM????

I am new to a lot of this, but the math just doesn't seem to come out right regardless.
