I use a set formula for the number of twists rather than go by a % reduction as most seem to do. The formula results in about an 18% reduction, pretty consistently.

John...

Since you do not go by % reduction, how do you determine how much length to add to the layout to allow for reduction? It seems to me that reduction has to figure into your process at some point. Admittedly, once that length is established, you can use it repeatedly without having to re-determine it for the same leader; but, that first determination seems to me to be mandatory.

Thanks!
