Question about starting hand chart

[Jailblazers]

I've recently started using a starting hand chart (shorthanded)

Got a couple questions about this one.

1. Is there a better one?

2. On some hands like A9s and A8s, it says if you are the opener that you should "raise first in or 2 limpers, call or check otherwise". But since we are the opener, this should be an automatic raise then. Typo maybe?

3. Under the small blind column, when it says 3B3 with AJ. I don't understand why we wouldn't 3-bet all the time. Are we losing money by raising (not 3-betting) in a 5-way pot?

4. On some hands like TT-99 and 88-77, it says that when facing a raise, you should 3B2-99. WTF does that mean?

5. Why is there no column for BB? I would assume that a lot of money is won/lost in that position. Like what hands should you raise with, 3-bet with, call a raise, or check with. No?
