[GreenKeys] Reading Teletype specifications is boring or not?

[w9ddd at tapr.org]

Until recently I thought high to low was like 100 down to 60 and low to high was 60 to 100.  I've since learned that one could have a LARP or a non-typing reperforator, which both have 200 wpm versions, as the input side.  Now I'm finding out what they really meant for high was a BRPE.  

Did they use a CX for low to high?

It appears Teletype R&D could come up with about anything for a paying customer.
