This is wrong in so many ways. I have to question if the author even knows what he’s attempting to explain.

The “French hotdog” (shown as Czech) was invented in Denmark in the 1980s. There are different claims of who made it first with minor details like how the bread is prepared. One of the guys claiming it also went on to invent the “double barrel french hotdog”.

No, it is the chart that is wrong.

It’s really simple and you dont need a chart: The shoe should be darker than the pants.

The intro in Dial of destiny happens somewhere in the French Alps and maybe Germany.

Yes, it has been observed that IMDb sometimes get a lot of new “single post users” putting in 10/10 ratings on Disney movies that otherwise scored badly.

It appears that the colours are not on a fixed scale. The season averages and individual episodes are coloured using different ranges.

It ranges from lowest to highest regardless of the value. Like conditional formatting in Excel does if you don’t specify the scale.

The seasons average ratings range from 6.1-8.4, so it goes red to green in the span of 2.3 points.

The episodes range from 3.9 to 9.3, so it goes red to green in the span of 5.4 points.

The full IMDb ratings range from 1-10. This should have been used as a basis for the colouring instead. The overall average on IMDb is somewhere around 7, so it would be fine to skew the colours so the middle/yellow was at 7, but it should be able to represent any possible ratings.
