That calculator is useless. The heat tolerance variation between different athletes is far to great for it to make a single prediction.
This. Here's a neat vid of Frank Shorter talking about the formation of the Florida Track Club in Gainesville. Skip to 7:30 for a specific reference to individual heat tolerance. But, the whole thing is worth a watch: (link)
First race was 102 degrees in the morning when sun was coming up.
102F in the morning? This is hell on earth. Move.
LOL you get used to it. It was actually nice that morning and didn't feel that bad (but for sure you'll run faster in real temperatures).
Can't move until my daughter finishes high school. Then probably back to the Seattle area, where we'll miss the 100 degree days when it's 38 degrees and pouring rain.

Heat tolerance also varies depending upon the acclimatization of the individual athlete.
That said, the calculator does presumably give some sort of population average, which one could argue is a more informative reference point (i.e. better than "useless") than "everybody is different" even if the population average comes with wide and unspecified population variance.

The population average is literally just all the athletes Jeff Gaudette has chosen to work directly with, most of which are no less than mid-pack and usually a good deal faster, and live/train in places with a similar climate, whether it's mild or cold all the time or muggy all the time like the south. He lives in Florida and doesn't have much applicable experience with climates that significantly differ like elsewhere. So it's based on a skewed relatively isolated sample.

Not in the middle of summer, try mid 90s. Once we start hitting low 80s in the morning we consider it to be decent weather. Nobody ever says a 102 degree morning is "nice" though nor does Phoenix ever really see that unless "morning" is 9am.
There's a small window just as the sun is coming up where the temp can be over 100 but not really direct sunlight, it's much more comfortable than an hour later, so it feels "nice".
Our kids get up at 5am to make it to summer practice at 5:50. Honestly I'm amazed at their dedication.
