For Ida Kamphuis: You are one of several people who pulled me up for writing 'There is no off Dyskinesia' - it is a very provocative statement. What I was trying to say, is that in MY world, there is no off dyskinesia. I don't presume to tell you how you feel. I feel that I am getting a better understanding of the way that you, and David Langridge, and many others for all I know, are indeed deliberately booting yourselves into what I called the Overdrive zone, or the Twilight Zone. I am still guessing to some extent,because you have not spelled out your tablet schedule: how much and when. You are correct in saying that my program will still work: You tell it what to aim at (i.e. what corresponds to zero on the condition scale ), and it tells you how to get there. It makes no judgement as to whether that is a good of bad place to be. I have already said that I found, when I tried it, that for me there was no relief to be found in the Twilight zone, but if it works for you, then that is what you want. What I am curious about, is whether the much lower flow rate at which I get my zero condition is accessible to you, but you don't see if because you are busy zooming up to the TZone, or whether my target area simply does not exist for you. Just a brief word about the program: some of the people who did fill out some data records, and send them back to me, presented me with a near-perfect zero +/- 0.5, over the whole day. I was left with nothing to analyse! What I want to see are your mistakes, showing you zooming all over the place. I learn more that way than I learn from a steady zero trace. I will be looking out for some data from you, and David, and anyone else who wants to have a go - What have you got to lose ? Regards, -- Brian Collins <[log in to unmask]>
