How often do males pop out when incubating at 80f?

So far looks like 3/4 are males when i incubated at 80f, took 53-55 days to hatch instead of 35 when i was incubating at 90f

I incubated at 80F almost exclusively for 13 years and had less than 10% of the geckos turn out to be male. The one year I incubated a bit higher I had a really hard time figuring out which ones were male. Is it possible you think some are male when they're female, or that possibly the actual temperature in the egg containers is higher than 80F?

I'm fairly certain, by 20 grams its pretty easy to see the bulges vs the ones without.. i have some ideas to try to hopefully equalize the temps better as the incubators mostly empty right now as well as adding a 3rd thermometer..
