If I understand the video sequences, the first one indicates that the new stat leaks water when closed, which doesn't bode well I'd say. Clearly, this stat when fitted has improved the running temperature over the old one, but won't get as high as it might due to the pre-opening leakage. Is this stat the rubber seated one or has it a formal bleed vent?

Thanks for doing the tests.
