Sensitivity analysis
What it means
Moving one assumption of the calculation at a time (how often your opponent folds, your equity, your realization, the stack, the size) until you find the value at which two lines tie: the break-even point. If your read on your opponent is far from that value, the choice holds up against read mistakes; if it's right next to it, either line is close.
Example
With J♥T♥ facing 9 bb into a pot of 13.5: the 33.5 bb all-in (40 bb stacks) beats calling if your opponent folds more than 38.21%; the 93.5 bb one (100 bb stacks), only if they fold more than 63.86%.
