Don't guess or make up your own methods for torquing rod bolts. This is the most critical torque spec on the entire engine.

Either use bolt stretch, (the only right way to do it really) or 15lb/ft, then 90 degrees. (more accurate than torque alone.

When torquing using the stretch gauge, I've come across a number of bolts that reached torque spec WAY before the bolt reached proper stretch. Why? Friction. I swapped to a different nut on the same rod bolt and this time it stretched to the proper spec without issue. The low torque, plus 90 degrees is more accurate because it relies less on the right amount of friction.
