I agree with the conversion rate above, but with one caveat: in D3, if the cost is close for both 2 CV's and 5 HV's, I always go with the HV's. The reason is you may only need (for example) 60% of that recruiting value to get the recruit you want. So you could get him for 3 HV's, but if you go all-CV, you'll still need 2 CV's. The smaller incremental cost of HV's often makes them, imho, a better value.
