If you want to knock off a SIM in the first cycle or two, five CVs are not nearly enough. I generally send 15, knowing some of them will be rejected and I will get the money back. Scheduling multiple CVs throughout isn't going to do it, either, because the SIMs are doing the same thing. You need to send a lot early, since the SIMs are putting money into the recruits every cycle and the cumulative effect can be difficult to overcome.
