With regards to points, it's a screwed up system that slightly favors the old guys that have been applying for decades while royally screwing over everyone else.
If you're looking at points, the best plan is to accumulate 2-4 points, use them on a unit, build points again and repeat. Do this in a few states and you have a good chance at a decent tag most years. Don't bother trying to get 14 points for that one awesome unit. In 14 years it'll take 22 points and so on.
Edit: I should note, by "slightly favors", I mean that say a true lottery system (like New Mexico) gives you a 3% chance of drawing. States with points systems give a 4% chance of drawing to folks with max points and a 0.2% chance of drawing to anyone more than a year or three behind them. I made up those numbers, but that's roughly how it works out. Screws over everyone not in on the ground floor while hardly benefitting those that have been in it since the first year or two.
