Yes you are, Arden. Front squats will naturally raise your back squat or keep it where it is at since it's so damn high. I'm pretty sure my back squat's gotten up there as a result of front squatting for the past 2 months. I'm using weights for FS I normally use to rep out on BS so I'm positive. I've also found that it's very important to push the knees out while FS'ing and OHS'ing and keep pushing even as you lock the weight out.
I wish I had a 250kg+ BS...
