Pretty much, but you can start at whatever level you feel comfortable with. I usually start out at least .25/50 because like POKher described if you get into a rut at one level it can be a frustrating. As far as when to stop goes, always set a target limit and stop when you hit it or wimp out. I've have never made it past 5/10 while shooting for 10/2 (b/c I suck!). I've never seen guidlines on when to stop short of your target but I wimp out when I fall to less than 12BB of the level below me. (e.g. @ 5/10, I'll stop if I fall to $48 (12 BB of 4/8)). I'm sure there are purists who will insist on hitting their goal or bust out - I hope to be there one day.
