Correct shortstack strategy

[Black winter day]

I've been trying to shortstack 8-10 tables lately (for my own reasons, let's not go into why right now), just wanted to make sure i am playing correct strategy.

I buy in for 20bb and open shove/3bet allin TT-QQ, AQ-AK, with KK-AA i might raise less, might also shove, depending on position, the players, etc.

If tight player raises from UTG, i might muck TT and AQ.If there is a raise and a reraise in front of me, i play AA-KK,AK, often QQ, depends on who is the reraiser.

If i am in SB and everyone folded, or in BB and SB limped, i obv shove AT+,88+, sometimes KQ,A5+ and 55+, also depends on the player.

On the button, first in - i shove 88+, AJ+.

Anything i am missing or is this pretty much it?
