Interesting proposition! Theoretically this may be achievable; but its use eludes me. Anyway, I would be interested to get this 'equation' too... even if it should only turn out to be one of those trivia, for even if everything were to remain constant (known), the temperature could hardly be assumed 'even' across the entire gel.
