Alot of rods carry surplus material over the cap. If it's properly butressed around the bolt, then it makes it stronger, but most aren't and have a neat stress raiser created by the rod bolt counterbore; like these "kit car" replica rods:
Also the reduced piston and rod mass of my designs reduce stress. If you take the peak inertia of a Wossner "Kit Car" piston and PEC rod at 9000rpm, mine won't see that until 10,000rpm on the same stroke. And because I target high torque figures over using revs to achieve power, my engines tend to be limited about 500rpm lower than others. The resulting inertia at the rev limit is about 27% less. That's a healthy margin of safety, before you consider the manufacturing/material quality and bolts.
