Why do you start this piece with rubato? This is not the first time I listened to a recording of this prelude on this website, only to hear it start with a strange rubato that doesn't make sense to me. The opening figuration is a figuration, it is not a beautiful melody. It should sound misty, fluttering, shimmering, like an enveloping fog. When you start with a rubato, it destroys the effect totally.
