ICMIZER Output Question

I'm a new user and unsure I'm understanding the output correctly.

I have the following situation. The HJ shoves and, it's folded to the BB. ICMIZER Bubble Factor says the BB needs 60% raw equity. It lists the HJ's range. Then shows ATo is a profitable call. I've entered the HJ's range vs ATo, and ATo only has 53% equity.

Am I misunderstanding the term "necessary raw equity"?

When I enter the BB's calling range, the entire range has 60% equity, but surely it's not using range vs range equity when we're closing the action all-in HU.

The only hands with => 60% equity vs HJ's range are: AA-TT, AKo, AKo-AQo.

Any insight?
