suited Ax equity v premium range

[sh58]

so people like 4bet shoving with Axs cos of the pretty good equity against a calling range from a TAG.

i used all suited aces and tested their equity against the tight range of: QQ+, AKs, AKo

i was just wandering if any of you maths boffins have an expanation for the strange ordering of the best equity's.

it is a bit irrelevant really as the differences involved are pretty much with 1.5% of each other but i am curious to know the reason. i suspected A2-A5 would fare best because of their wheel potential but what about the others, and AQ is obviously bad because trip Q's isn't as likely cos of QQ blocking it.

here is the order

AK (ldo)
A5 - 30.2%
A4
A3
AT
A7
AJ
A2
A8
A6
A9
AQ - 28.6%

so why this order?

Straights.

A5 makes the most straights, one 3card straight, 3 4card straights.
A9 for example makes no 3card straights and 2 of its 4card straights are blocked by QQ and KK.
