probably 4 or 5 percent below what you were when we took our pre-flights, and those were very constant, especially the first two.

Well, if we are still 4 or 5 percent down, then we only went down about 8 percent.

Right.

What is the sensitivity in your method?

Well, as I pointed out this morning, it depends on the situation, but we think we are definitely within 5 percent. It - we produced it on several machines - many times we get much closer than that, but we are not - we don't want to go out and say that we are - it varies.

What was your experience with the exercise?

Yes, well let me comment on this first, because I think I deviated further the experiment. But after about 2 days I felt that I wasn't getting any exercise at all, and there is a limit to how much pushing on the floor that you can do, so I got clearance from Dr. Grady, to go ahead and use the exerciser throughout the remainder of the flight. Not only as a method of exercise as prescribed in our medical type 1 passes, but also as a form of exercising my arms and legs, however I saw fit. And I did do this through the remainder of the flight. I think the reason I did this, I sort of felt it was advantageous to go 4 days and be capable to get outside the spacecraft by myself than to sort of stay in the state of hibernation. I kind of liked your comment yesterday, something about rather than turning into a pumpkin. Something like that, I thought it was funny.

Really, we were - I was getting much less exercise than I had anticipated. There was a spurt early in the flight when I was getting everything out, getting everything stored before the EVA and we
