I'm not just including precision, but ability to get through defenses - i.e. total battlefield effectiveness. Precision in terms of "circular error probability" isn't the biggest issue now. Its the EW environment. My point was if system A gets through defenses 30% of the time, but is 10x cheaper than system B which gets through 80% of the time. System A is generally the better choice, except for some very specific circumstances, very high value targets with limited strike opportunity.
