<p>LOA, only need one.
No LOA, having more than one probably gives you a bit of a better chance because it gives the Academy more options. If you only have one nom and its from MOC 1, you’re only chance of an appointment is from MOC 1’s pool. If you have one from MOC1 and another from MOC 2, the Academy may see you as the most competitive in MOC 2’s pool but not MOC 1. In the first case, you don’t get an appointment. In the second case, you do. This is, of course, if the MOC just submits 10 unranked names.</p>
<p>Hopefully that’s all correct. Forgive me if I made a mistake; this stuff is still confusing :D</p>
