when should a guy take a look at rod bearings (mainly for squish or wear)

on my proextreme car at 60 psi with c screw blower we look and change rod bearings every weekend and
change rods every 25-30 runs


my apex is supercharged 12-14 psi boost 3 head gaskets 4000 miles on this engine
clutched 10200-10800 depending on air and conditions, pump gas, trail riden agressivly
in the up, stock pistons and rods, up graded fuel pump so i think ive got a happy engine
with no lean spots or detonation(death of 1st engine was comp and low fuel pressureat 500 miles)
