you made me rethink how I cook my pasta and researched a little bit. The effect I'm experiencing can be explained by the amount of water I use. I always used 3 liters of water for 500g spaghetti. Recommended are 1l per 100g. Using lesser can result in greater loss of heat when putting in the pasta into the water.

I was thinking maybe elevation was accounting for the discrepancy, but thus makes more sense! Thanks for doing the research and solving the mystery.
