Note that those times are for rotary development with prewash. Without the prewash, you probably want to reduce the times by at least a minute. I use prewashing because I develop in (often wet) Expert drums, for which there is the risk of highly unsightly dribbles of uneven development unless you get the whole emulsion swollen before starting development.
