t/e = throat/erosion the higher this # the less meterial is left before the rifling starts so the bullet must jump farther into the bore.
m/e = muzzle/erosion or muzzle/wear is almost the same in that the higher the # the more gas gets past the bullet giving it lower velosity and reduced accuracy so the barrel has a hard time stablizing the projectile.
This is IMHO for what its worth others here can explain it much better than me, it is also my opinion the m/w is more detramental to accuracy than t/e
