But it certainly is in the case we are talking about. Imagine if a exercis= e machine display updated often to show "instantaneous" power. People would be upset that the reading jumped around a lot and was hard to read. A second peak-holding display would cost more and confuse people since it had no real benefit. And then there is the big question about what exactly "instantaneous" means. The power output is a bit like a fractal in that it gets rougher the closer you look to some extent. > My point is simply what if someone wants to know their maximum > instantaneous power attained? Then they're being silly, at least for the applications these machines are designed for. But again, what is "instantaneous"? 100ms, 10ms, 1ms? Also, as the time period gets shorter much of the apparent power is likely coming from momentum effects. For example, I can appear to put out a lot o= f power for a short time by climbing on a chair then jumping down on something. However, this is just release of stored energy (potential in this case) that my body put out earlier over a longer time period. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
