Looking at AF's E-170 regional planes.

Is seatguru.com correct in that the seat pitch is much bigger in rows 1-5 than from row 6 onwards? Just wanted to double-check with you guys, as seatguru is frequently wrong.

I'm flying eco and can pre-select rows 4+5 for free. I know these Embraer flights tend to be short ones so it's no big deal. Just curious as there's always a risk of being reseated due to the moving divider when selecting an eco seat very much near the front of the cabin...
