Aha! It took me a while to figure out what you meant here, but now I see.
What a good solution! Kind of obvious too, but sometimes I miss the
obvious.
How do you know what the actual speed is, though? I can kind of tell with
the 1 second setting that it's actually 2 seconds, and that the 1/2 second
is somewhere in between 1/2 second and a full second, but I have no idea
what 1/4 is really.
I guess this is where the tool that Richard mentioned from Calumet comes in
handy.

OK, I'll try that today. It would be good to internalize those speeds.
Right now I'm not even sure of my ability to count off whole seconds
accurately. (Christopher James recommends saying, "One Ansel Adams, Two
Ansel Adams...")
