Re: speed: good question from kohai
I agree with Keith's post above. Speaking for myself, I'm consumed these days with just trying to move as one body, rather than being led by my feet, or hands, or head, or chest, etc.
What makes it all the more frustrating is that I believe that one has to do something correct first on accident, before it can be done correct on purpose. Progress in aikido comes from experience, not observation...
So, to attempt to answer the initial question, these days, I'm probably 90% slow (meaning attempting to be correct), 8% seiza (watching, and trying to "steal" details from Sensei), and 2% fast (but most likely incorrect...)
