1) I believe that your front squat is supposed to be about 80% of your back squat.
I remember that Dan John has a diagram on his site that indicates what your front and back squat, clean, power clean, snatch, and overhead squat should be like in order to have a balanced physique. It's called the X-diagram, I think. I'm sorry I can't be more detailed, but if you poke around his site, I'm sure you'll find it.
2) I haven't done front squats by themselves in a while. I do cleans instead. I haven't tested maxes recently either.
I just cleaned 220lbs yesterday (yay, almost two wheels), which would imply at least a 220lb front squat for a triple, although I've done 235lbs for front squat triple before. For my back squat, I most recently did three reps at 265lbs as part of a workout.
235/265 ~ 88%, but my posterior chain and core strength aren't great (still working on it).
BW 170-175 (closer to 175, actually).
