I suspect mine is doing the same thing. Ford's DCT literature talks about "microslip" technology where some clutch slippage is allowed or induced to make the experience smoother. So the debate could be whether this degree of slippage is a feature or a bug.
Dealers can hook a recording device to the OBD port. Much like a heart monitor, if an irregularity is noted during a test drive pushing a button will preserve that data. This is the next step for my car; armed with your data maybe you could suggest the same to your dealer.
