Now you're just being thick. He never said what you say he said. What he did say is that you can safely include the figures from the late 19th century to the present in reference to the albedo of Venus. The methods used to measure albedo at that time are as valid as they are today, and no one said today's measurements obviated, or even contradicted the earlier measurements -- that seems to be something you came up with all on your own in an effort to bolster a hypothesis that has very little going for it. If you need to cook the numbers and dream up "conspiracies" by the scientific community to make a case for your pet hypothesis, maybe it's time to take a good look at what you are trying to prove.

Sorry, but that's flagrant BS. You're going to tell me that measurements taken from Earth starting in the 1800's are as good as measurements taken in 1978 from orbitting vehicles right on top of the planet? The only meaningful way to even talk about averaging anything would be averaging measurements taken from orbit STARTING FROM 1978; anything prior to that you throw away.
