Alright. I just ran through all modes.
1/4 - Short, Medium, Long are all as expected.
1/8 - Short, Medium, Long are all as expected.
1/16 - Short is short, Medium and Long are the same.
1/32 - Short is long, Medium and Long are the same (short).
Thanks for the explanation about why I only get two divisions in 1/32 step mode. Is it also supposed to be this way for 1/16? I'm guessing yes, because that is what I'm getting.
