.015-.020 offset is sufficient for #10 & 1/4" fasteners. Based on that; marginally increasing the ratio for larger screws works too. To increase clamping 'range', instead of making increasingly offset screws; offset the hole in the bite clamp. Biased toward one corner, but asymmetrical yields, 2,3, or 4 distances from the screw centerline.
