Yeah isn't like baking a cake - put stuff in the oven, set a timer and done lol.I think it's more like it is very hard to be accurate with this, so it is better to not promise anything.
You think a problem is easy to fix and take X days, and then you realise there are unexpected complications and it takes twice as long as you think. Then in testing they find that it causes a conflict with something else or it's not quite as polished and need re-working. Dev always takes longer than expected on complicated stuff like this game.
