It's somewhat entertaining to watch, but with a sample size of one, his tests are worthless, and in some cases methodologically flawed, I don't remember what he was testing but he measured the temperature of a law mower engine as part of something he was testing, but it was outdoors and clearly during different times of day for different tests, he really needed to measure delta T over ambient becuase the difference in outdoor temperature through out the day in Missouri could easily have accounted for the differences in engine operating temperature
You are right. They absolutely aren't controlled scientific tests. No doubt about it.
I recently watched glue and construction adhesive tests. He used wood blocks cut in 1/2 and then glued back together so that he was dealing with consistent wood at the glue line.
However, he also did 3 blocks per glue/adhesive because he recognized that any single block of wood might be different than another.
Even with that 3 blocks per glue brand , he encountered wildly different failure points. There's no way that would be considered scientific.
He'd have to do 100s/1000s to start seeing valid trends.
But... it allowed me to see that one brand of marine adhesive is probably much better in general than the the brand shown on TV that allows you to make a boat out of a screen door.
And it was entertaining..
For me it's a combination of entertainment (Heck I've watched like 100 brake job videos for cars I don't own!!) and a chance to learn and thing about things.
