That "tiny extra fabric" point really hits home. Was there a particular type of fitted garment, like a blazer or a dress, where you found the wider allowance made the biggest difference? I'm always trying to pinpoint which projects are worth the extra material upfront.
Actually, trousers were a game changer for me with wider allowances. That extra bit let me fix a too-tight waistband without starting over, which saved the whole project. Having room to adjust completely changes how stressful a fitting feels.
