In other words, the more followers an eBay auction house has, the higher prices they will achieve, all other things remaining the same.

That is his claim, anyways, as he hasn't actually presented any proof that would substantiate it. Nor has he addressed what they teach you on the first day of Data Analysis 101: correlation is not necessarily causation.



I spent the first two decades of my professional career in electronics manufacturing and the most recent decade in oil and gas. Both are industries dominated by engineers. Indeed, my background is engineering. It is my observation that folks with technological backgrounds often assume that, because they have mastered one (or several) difficult subject matters, that they can reason their way to correct answers beyond those areas. So, go easy on him because he is a victim of his programming.

On a lighter note, I thought I'd share with Snowman how us grayheads used to bid on card auctions outside our hometown back in the day,

I know what you are saying and understand exactly what he does. I did point out his own posted figures and asked why his own evidence doesn't support his statement that PWCC has the highest prices because Probstein actually has more followers. And there is no reason to go easy on him as he is obviously knowledgable, just doesn' t really say anything that basically ends up as anything other than he's right and you're wrong. Same thing you're pointing out. And just because he's an engineer he gets no pass from me. I've worked with many engineers and architects in the past, and engineers are typically very knowledgable and pay attention to details and facts. And my daughter is an engineer as well. Feel I'd be letting them all down if I didn't call him out.
