Subliminal priming?
Is that like when a major news network runs the caption "Mark Foley (D-FL)"
under images of a disgraced ex-congressman (who is actually Republican)?
[Apologies!]
To answer your question, I've tried using "milliseconds" and "ticks" in
combination with the "wait" and "send xxx in nn" commands and had very
inconsistent results controlling on-screen animation/activity when the
values were small. Perhaps if the script were extremely simple and it was a
virgin install of the operating system, the results would be more
consistent.
If you are trying to strictly control the amount of time a subliminal
message appears on-screen (for example to determine the threshold of
perception) I am not sure you will be able to do this accurately, to
scientific/laboratory standards, with Rev.
You will also need to consider the monitor refresh rate, which could be
anything from 50 Hz to 120 Hz. I do not believe this can be controlled or
sensed from within Rev.
