@polotek@social.polotek.net I use Jacob Kaplan-Moss' technique as a reference. This was eye opening when I found it because it was the most rigorous framework I found that felt realistic for software dev. Over my career I've developed a rule of thumb to double whatever my initial gut instinct is if I'm providing a ballpark. This has been shockingly accurate for smaller, less complicated work. https://jacobian.org/2021/may/25/my-estimation-technique/
