Only 2 gussets for the Chubby Hatch?

I've followed Kuffel Creek "reasonably" close so far for my Chubby. The plans show only 2 gussets (one on each side) to hold the curve for the Hatch. I've noticed multiple gussets on the hatches shown on the forum and build sites.
Anyone had any problems with only two gussets? Not that big a problem to add more if it's necessary. I'll be skinning it with 1/8 inch Luan on the outside and 1/8 " birch on the inside.
