I'm wondering if anyone knows of a solution that works for various temperatures of a specific volume or similar equations.

if there was then whats the point of the event

I tend to just derive my k value of my device (via multiple trials over different temperatures and time spans) and then use that, trial data, and gut feelings to intuit what the final temperature will be.

Note that there are always just too many variables to factor in. No simple equation would be capable of calculating temp accurately given all those variables. Only multiple tests of your device will provide an accurate estimation.

That or they use a more calibrated and accurate thermometer than yours. Or the other way around...
