Setting Specific Goals for Progress (Advice needed)

[Muscle_4_Hire]

Okay, so I've been searching a while for general goals for bodybuilding so I can make them into my own specific goals. However, no luck. For instance, what I want is to see somebody say "training naturally, it is average for an intermediate meso-ecto to gain .5 inches on his arms in 12 weeks time if the athlete trains and eats well." So I would make .5 inches the bare minumum I have to achieve in 12 weeks.

I need goals to shoot for. I have plenty of ways of tracking them i.e. bodyfat analyzer, measuring tape, scale, pictures, comparison in workout journal, etc.

However, what I need is something like "For a natural bodybuilder in a 12 week bulking period, it is average for them to gain .5 inches on their arms, 1 inch on each leg, gain this much muscle, etc."

Thanks for any advice.
