If burmese eggs are incubated at 86 F, you would be very lucky if the young hatched at all, let alone without developmental abnormalities. I know of a clutch of burmese eggs incubated at 85 F, and all the eggs failed to hatch, and all died in the egg. Almost all python species require at least 86 F for incubation success, and I agree with your friend that the vast majority of python species eggs would not survive if incubated over 91 F. However, the molurus group (Burmese, Indian, Sri Lanka) requires higher incubation temps than any other python species. Female molurus hold the egg mass at an average temp of 91 to 92 F for virtually all of the incubation period, and will occasionally hit 93 F for short periods. I have personally measured inter-coil temps with Burmese and Sri Lanka females while maternally incubating and can confirm these temps. It is an adaptation to higher latitude, cooler climate survival. Most burmese eggs are artificially incubated at 90 F and this seems to work well, especially if you are unsure about the accuracy of your temp measurement device. I would not recommend going any cooler than this for burmese. However, definitely make sure that your thermometers are reading accurately.
