Maybe not if already steeped in the current system, but if starting from scratch, one would play the note written, each and every time. It's a bit like reforming spelling. We (the Old Folks...) are quite used to the anomalies, but how to explain the logic behind the pronunciation of Cholmondeley, for instance..? Those 'in the know' find it to be instinctive, but it's daft, really. Still, I'll be thanked for the idea only posthumously, I fear.
