I believe the temperatures within the chart are “feels like” temperatures rather than absolute temperatures. The X axis shows absolute values (what would likely show on the thermostat).
At OPs original temperature (91°F) the danger zone would be around 60-70% and higher. At OPs last updated temperature (94°F), the danger zone would be 55% or higher.
I mean they usually only do about 30 damage anyways.
